A note on photography, printed because this page believes in saying so: our photo bank holds no undershirt photography, so no ranked garment is pictured anywhere on this page. The hero is a white crew neck worn as a top, the undershirt's outerwear sibling and the garment every layer below is graded against, captioned as what it is. The frames this page actually needs, a collar hidden under an open shirt, a sleeve line failing under a dress shirt, a hem still tucked at the end of a day, head the harvest list in the honesty section.
Checked and updated October 2026
The verdict, up front: seven undershirts, scored out of 100 on the house basis for this category: cloth 30, construction 20, fit and stay 20, value 15, longevity and wash 15. The Tommy John Second Skin Crew Neck Stay-Tucked wins at 85: the only garment in the field engineered, piece by piece, for the three tests below. And the Tom Ford underwear crew neck, at about $116, is sent home at 47. This page completes the base-layer system: the underwear ranking graded what sits at the waist, the boxer ranking graded the loose leg, the tank ranking graded the sleeveless layer, and this one grades the layer with sleeves.
First, the decision
An undershirt is the only garment in the wardrobe whose success is measured in invisibility. The ruling, in one line: an undershirt succeeds when nobody ever sees it: no neckline inside an open collar, no sleeve line through the shirt above it, no untucked tail by 3pm. Three tests, and every score on this page is downstream of them. The neckline test is the defining one: open two buttons on a dress shirt and look. If a ring of undershirt shows in the opening, the garment has failed at the exact moment it was bought for. The sleeve test is quieter: a sleeve cut too long prints its edge through a dress shirt's arm like a second cuff. The tuck test is the slow one: length and taper decide whether the hem is still where you left it after a day of reaching, sitting and standing.
This is where the undershirt parts company with its sibling. Our white t-shirt ranking grades a garment built to be seen: cloth weight for opacity, a collar that holds a ring in public, the Asket tee winning at 88 as outerwear. Nothing from that page transfers here. A tee's virtues are an undershirt's vices: weight becomes bulk, a proud collar becomes a visible one, a boxy body becomes a tail by 3pm. Same drawer, opposite grading, and the two pages are written to be read as a pair: buy the tee to be looked at, buy the undershirt to disappear.
The moisture claims get graded the way this site grades them everywhere, as garment physics only. An undershirt does three honest jobs with sweat: it absorbs it (cellulosic fibres, modal and bamboo viscose, take moisture into the fibre), it transports it (polyester knits spread liquid so it evaporates), and it takes the stain so your dress shirt does not. It does not cool you, block you, or shield you, and where a maker sells one of those words, the cloth row grades the fibre line underneath the word. If you buy one undershirt, buy the Tommy John. If you buy the argument, buy any of the top three and run the three tests in the first mirror you pass.
How the scores work
Five rows, printed on every card, the same discipline this magazine applies to a $500 shoe and a $3 undershirt. Cloth judges the fibre and the knit as the maker publishes them: cotton against micromodal against mesh synthetics, weight where a weight is published, and a published weight beats an adjective every time. Construction judges the collar first, its depth and whether it stays hidden and flat, then the sleeve length against the show-through line, then the seams. Fit and stay is the tuck row: published length, taper, and whether the body holds its place without compression, because a stretched garment pulls toward its unstretched shape and rides up faster, not slower. Value divides what you get by what you pay per shirt, packs divided openly, against the whole field. Longevity and wash costs the two ways an undershirt dies: the collar sagging into waves, and the white going yellow at the underarm. The rows sum to the score, and the score is printed where you can screenshot it, under our published methodology.
Seven undershirts, ranked
Tommy John: Second Skin Crew Neck Stay-Tucked Undershirt
Best overall
List price at last check: $43 for a single in the US; the three-pack lists at $129, the same $43 a shirt.
The call: buy it first. The undershirt as an engineered answer to the three tests.
Tommy John built the company on this garment, and the published spec reads like a point-by-point reply to the ruling above. The cloth is 90 percent non-pilling micro modal and 10 percent spandex on the maker's own materials line: a cellulosic fibre that absorbs moisture into itself, knitted fine enough to sit flat under a dress shirt. The collar is the maker's memory collar, a stretch rib designed to lie flat and keep its ring wash after wash, which is the construction row's whole argument in this category. The body is tapered rather than boxy, and the length is the maker's patented stay-tucked design, extra hem below the waistband with the taper to hold it there. Nineteen of 20 on fit and stay is not enthusiasm; it is the score a garment gets when every published dimension is aimed at the test.
The deductions are printed with the praise. Forty-three dollars is the highest honest price on this page, and the pack arithmetic does not rescue it: the three-pack costs the same per shirt, so the value row grades a single at single money, 10. Modal publishes no cloth weight here, and on a page that prints weights the absence costs cloth points, the same charge this site lays on every maker who asks to be graded on adjectives. And the crew neck is the dress-shirt cut; worn under two open buttons it will show, because that is the V-neck's job, and the maker sells the same garment in a deep V for exactly that opening.
Sunspel: Superfine Cotton Underwear T-Shirt
The cloth winner
List price at last check: $65 in the US at Sunspel.
The call: buy it when the cloth is the point. The finest published fibre in the field, worn against the skin.
The cotton classic done properly, from the house that has made underlayers in Long Eaton since 1860 and graded its way to the top of two other pages in this system: its boxer short scored 81 on our boxer ranking and its sleeveless vest won the tank ranking at 84, both cited as brand evidence only, because this garment is scored fresh. The cloth is the house's Q82 superfine jersey, long-staple cotton spun two-ply, the ply being the detail that matters in a layer: it buys durability the single-ply fine jerseys cannot, at a hand feel none of the synthetics here imitate. The neckline is bound in the underwear tradition the house inherited, thin enough to hide in plain sight under a shirt, and the fit is a true layer's fit, close without stretch doing the work.
What keeps it second is the category's own arithmetic. There is no stay-tucked engineering here, no extra length programme, no memory collar: the fit and stay row, 16, grades a well-cut standard garment against a field that includes a patented one. At $65 it is also the most expensive honest shirt on the page, and cotton's known tax applies: it yellows at the underarm sooner than the synthetics and sags at the collar sooner than the modal, both priced into the longevity row rather than discovered later. Buy it for the cloth. Know what the cloth costs.
Uniqlo: AIRism Crew Neck T-Shirt
Best under $15
List price at last check: $14.90 in the US.
The call: buy three. The attainable pick, and the best disappearing act per dollar on this page.
Scored fresh, as the law of this site requires: Uniqlo the brand stands at 84 in our brand rankings, its AIRism boxer brief scored 78 as a garment on the underwear ranking, and its AIRism-adjacent ribbed tank scored 77 on the tank ranking, and none of those numbers is inherited here. This garment earns its own 79. The cloth is the maker's AIRism knit, polyester and spandex developed with Toray, published at 89 and 11 percent in the maker's line spec, with the quick-dry, cool-touch and deodorizing functions the maker prints on the product page. The maker's own description says the fitted cut stays hidden under outer layers, and for once the copy is the spec: the body is cut close, the collar sits flat, and the length runs long enough to stay tucked through a workday. Fit and stay, 18, at $14.90 is the best ratio in the field.
The charges are the fibre's own. Polyester absorbs almost nothing; it transports, which means the sweat leaves your skin and the odour stays in the shirt across a season in a way the cellulosic fibres above it do not hold. The longevity row, 9, is that sentence as a number. The US product page also declines to print a cloth weight, where the maker's figure for the line, about 115 gsm, circulates through its other markets: graded as reported, and charged as unpublished where it counts. Buy it as the rotation layer, in the colours of the shirts it hides under, and replace without ceremony when the nose says so.
Mr. Davis: Bamboo Undershirt
The bamboo altitude
List price at last check: $34 for a single in the US, less per shirt in the maker's multi-packs.
The call: buy it if you are tall, or if your undershirts have always been too short. The length specialist.
The independent undershirt makers are this category's craft tier, and Mr. Davis publishes like it knows it is being graded: 96 percent bamboo viscose and 4 percent spandex on the maker's own composition line, OEKO-TEX Standard 100 certified cloth, flatlock seams that lie flat against the skin, and a collar whose blend is published separately from the body's, 67.5 percent bamboo viscose, 27.5 percent cotton, 5 percent spandex, because the collar is where undershirts go to die and this maker has read the same autopsy reports we have. The cut comes in two shapes, traditional and tailored, and the length runs to sizes built for tall frames, up to a 35-inch body in the largest traditional cut. Fit and stay, 17, is earned on published inches.
The honest charges: bamboo viscose is a soft fibre with a middleweight's durability, and the maker's own care instructions, cold wash, low dry, hang the crew necks, admit the collar needs protecting, which the longevity row prices at 10. At $34 a single it sits in the gap between the Uniqlo's volume and the Tommy John's engineering, better published than both on cloth, less proven than either at scale. The class it belongs to, the bamboo and modal independents that David Archy's three-packs lead by volume, is graded here on the garment whose maker publishes everything and sells it direct.
Pact: Organic Cotton Stretch-Fit Crew Neck Undershirt
The organic pick
List price at last check: $29.99 for a two-pack at Target, $15.00 a shirt.
The call: buy it when the fibre line is the point. A real undershirt, cut as one, in certified organic cloth.
The organic entrant, verified the way this desk verifies: on the maker's published numbers. The cloth is 95 percent GOTS-certified organic cotton and 5 percent elastane, sewn in a Fair Trade Certified factory, and unlike several organic tees that get sold as layers, this garment is designed as an undershirt: a longer length with a straight hem that the maker builds to stay tucked, in the maker's own words. The cloth is on the thicker side for the category, which the reviews on the retailer's page confirm and the cloth row rewards: organic cotton with body to it absorbs like cotton should and reads as a garment, not a film. It is the only certified-organic cloth in the field, and the second GOTS garment in this base-layer system after the underwear ranking's winner.
The deductions: the collar is a standard crew construction without the flat-stay engineering the top of this page is built on, and the fit is a general stretch fit rather than a tapered stay system, so construction and fit grade as honest mid-field, 13 and 14. Cotton's taxes apply here too, yellowing and collar fatigue, priced in the longevity row. At $15 a shirt inside the two-pack it is the cheapest way to put certified cloth against your skin all day, and the value row says so.
Hanes: Cotton Crewneck Undershirt, 6-Pack
The workhorse
List price at last check: $20 for a pack of six at Target, $3.33 a shirt.
The call: buy the pack. The floor of this ranking, and the floor is a drawer stocked for twenty dollars.
The default undershirt of the last half-century, graded without nostalgia: 100 percent cotton in the whites on the maker's listing, tagless, with the maker's Cool Comfort moisture finish, which is a treatment on a cotton shirt and is graded as one, a sentence of physics rather than a fibre. To its credit, the maker's own copy lists an extra-long length designed to stay tucked, and the fit row credits it, 13: the modern Hanes crew is longer than the garment its reputation was built on. Nothing about the cloth is refined and nothing pretends to be; the material row scores it 16 the way the same house's ribbed tank was scored on the tank ranking, without apology.
Then the two known deaths, priced in advance. The collar is the category's standard failure, a plain crew ring that relaxes into waves across a season of hot washes, and the white yellows at the underarm on the standard schedule. Longevity, 8, is those two sentences as a number. And still: $3.33 a shirt, two cents a wear, a six-pack that fills the drawer for the price of half a Tommy John. As the layer under work shirts that are themselves headed for a hard life, it is not a compromise. It is the correct tool, bought in the quantity the tool is used in.
Tom Ford: Cotton-Modal Underwear Crew-Neck T-Shirt
Skip it
List price at last check: about $116 at Lord & Taylor; the same line's stretch jersey tee lists at $130 at Neiman Marcus.
The call: skip it. A dress-shirt price for the one garment nobody is supposed to see.
Grade the garment, as this page grades everything: a fine-knit underwear crew neck in a cotton, modal and elastane blend, flat seams, a slim body-hugging cut, per the retail listings for the maker's underwear line. Nothing in that sentence is bad cloth. All of it is ordinary cloth, the same fibre classes ranked above it at $15, $34 and $43, with no published weight, no stay-tucked system, no collar technology, nothing in the spec that a spec can point to. What the price buys is the name inside the collar of a garment whose entire job, by the ruling at the top of this page, is never to be seen. At about $116 it costs more than the dress shirts most men wear over it, 58 cents a wear against the winner's 17, for a layer that succeeds by disappearing. The logo tax found its purest form on the tank ranking, a mark dyed invisible at $480. This is its tailored cousin: no mark at all, just the receipt.
The cloth, in numbers
| Undershirt | Fibre and knit, as published | Published weight | Sold as |
|---|---|---|---|
| Tommy John Second Skin Crew | Micro modal jersey, 90% modal, 10% spandex | Not published | Singles and 3-packs, same price per shirt |
| Sunspel Superfine Underwear T-Shirt | Long-staple cotton jersey, two-ply (Q82) | Not published | Single |
| Uniqlo AIRism Crew Neck | Polyester/spandex knit, maker's line spec 89/11, Toray-developed | About 115 gsm in the maker's line figures; not printed on the US page | Single |
| Mr. Davis Bamboo Undershirt | Bamboo viscose jersey, 96% viscose, 4% spandex, OEKO-TEX certified | Not published | Singles and multi-packs |
| Pact Organic Stretch-Fit Crew | Organic cotton jersey, 95% GOTS-certified organic cotton, 5% elastane | Not published | 2-pack |
| Hanes Crewneck 6-Pack | Cotton jersey, 100% cotton (whites), wicking finish | Not published | 6-pack |
| Tom Ford Underwear Crew Neck | Fine knit, cotton/modal/elastane per retail listings | Not published | Single |
Nobody in this field publishes a cloth weight on their US product page, not one garment in seven, which makes the undershirt the least documented layer in the wardrobe. The pattern from the tee ranking holds with the volume down: weights are published when they flatter, and in a category bought by the pack, they mostly do not get the chance.
What each undershirt costs per wear
The maths, assumptions printed. An undershirt in a work rotation is worn about twice a week, call it 100 wears a year. Expected life is estimated from construction class, not from the price tag: memory collars and two-ply cloth at the top, plain crew rings at the bottom. Packs are divided into singles before any dividing happens, because a pack price quoted whole is how a $3.33 shirt gets compared against a $43 one by accident. These are the data team's estimates, published so you can argue with them.
| Undershirt | Price per shirt | Expected life | Cost per wear |
|---|---|---|---|
| Hanes Crewneck (per shirt) | $3.33 | 1.5 years | $0.02 |
| Uniqlo AIRism Crew Neck | $14.90 | 2 years | $0.07 |
| Pact Organic Stretch-Fit (per shirt) | $15.00 | 2 years | $0.08 |
| Mr. Davis Bamboo | $34 | 2 years | $0.17 |
| Tommy John Second Skin Crew | $43 | 2.5 years | $0.17 |
| Sunspel Superfine Underwear T-Shirt | $65 | 3 years | $0.22 |
| Tom Ford Underwear Crew Neck | About $116 | 2 years | $0.58 |
Read the packs column honestly and the field rearranges itself: the Hanes six-pack stocks a week of layers for $20, the Pact two-pack puts certified organic cloth at $15 a shirt, and the winner's three-pack offers no discount at all, $43 a shirt in any quantity, which is either confidence or arithmetic, and on this page it is graded as both. The Tom Ford line is the argument's end: at 58 cents a wear it costs more per day than the dress shirt above it in most wardrobes, for a garment that succeeds only when it is never noticed.
The Skip · 47/100
The Tom Ford underwear crew neck, at about $116, is this ranking's named loser. An undershirt is graded on disappearance: hidden collar, no sleeve line, still tucked at 3pm. On every one of those tests this garment is an ordinary fine-knit layer in ordinary fibre classes, cotton, modal and elastane, with no published weight, no stay system and no collar programme. What remains after the grading is the price, and the price is a name placed where no one will ever see it, which makes this the category's purest logo tax: the logo is not even printed. Buy the Tommy John for the engineering, the Sunspel for the cloth, the Uniqlo for the rotation, and keep the change where it can be seen.
The first wash, read from the specs
An honesty note, because this page prints its methods: the checks below are how to judge any undershirt after its first washes, together with what each construction on this page predicts. This is a reading of published specifications, not a laboratory result, and we label it that way because the difference matters.
Collar sag. Hold the washed shirt up by the shoulders and look at the ring. A stretch rib collar with elastane in its blend, the Tommy John's memory collar and the Mr. Davis's published collar blend, snaps back to its cut line. A plain cotton crew ring, the Hanes and the Pact, relaxes a little with every hot wash and ripples by the season's end. The bound neckline in the underwear tradition, the Sunspel's, holds its shape longest of the cotton constructions and then softens rather than waves, which is the two-ply cloth earning its row.
Sleeve creep. Measure the sleeve against your upper arm under a shirt. The failure is an edge that prints through: sleeves cut to outerwear length show a line at the bicep, and the fitted cuts on this page, Tommy John, Uniqlo and Mr. Davis, are published shorter and closer for exactly that reason. If a maker's size chart does not list a sleeve length, that silence is data, and the cloth-in-numbers table prints it as found.
The yellow test. Check the underarm against the light after a month. Cotton takes the stain where antiperspirant and sweat react, and takes it honestly, rinsing cleaner for longer before it sets. The synthetics resist the yellow and keep the odour instead, the AIRism's known trade, priced in its longevity row. Neither failure is a scandal. Both are schedules, and a ranking that prints the schedule is worth more than one that prints a star rating.
Which one to buy
If you buy one: the Tommy John, in the neckline your shirts demand, crew under a closed collar, deep V under an open one. If the cloth is the point: the Sunspel, and accept the standard length as the price of the two-ply jersey. If you are building a rotation: the Uniqlo, three to five deep, in white and the beige that disappears under white shirts. If you are tall: the Mr. Davis, the only maker here publishing lengths up to 35 inches. If the fibre line is the point: the Pact, certified organic at $15 a shirt. If you are stocking a drawer: the Hanes six-pack, replaced on schedule without grief. The ranking is a ladder, not a fence.
Questions, answered
What is the best undershirt for men?
The Tommy John Second Skin Crew Neck Stay-Tucked, scored 85 out of 100. It wins on the three tests this category is graded on: a memory collar that stays flat and hidden, a tapered body with no sleeve line under a shirt, and a patented extra length that is still tucked at the end of a workday. The cloth is 90 percent micro modal and 10 percent spandex on the maker's published spec, at $43 a shirt, about 17 cents a wear across two and a half years. The Sunspel Superfine Cotton Underwear T-Shirt is second at 83 and wins the cloth row outright.
Crew neck or V-neck undershirt: which should you wear?
The shirt above it decides. Under a closed collar, with or without a tie, a crew neck is correct and its ring sits where the shirt's own collar band hides it. Under an open collar, one or two buttons undone, a crew neck's ring shows in the opening and reads as underwear on display; that is the V-neck's job, and the deep V exists for the two-button opening. Every maker ranked here sells both cuts of the same garment, so the ruling costs nothing to follow: match the neckline to the opening it has to hide inside.
Why does my undershirt keep coming untucked?
Length and shape, in that order. An undershirt stays tucked when its hem sits several inches below the waistband and its body tapers enough that the cloth has nowhere to travel. A boxy undershirt cut to outerwear length rides up a fraction with every reach and sit, and by mid-afternoon the fractions have added up to a tail. Compression is not the fix; a tighter shirt rides up faster, because stretched cloth pulls toward its unstretched shape. The two longest, most tapered garments on this page, Tommy John and Mr. Davis, hold the two highest fit and stay scores for exactly this reason.
Do moisture-wicking undershirts actually keep you cooler?
They manage sweat; they do not refrigerate. Graded as physics: cellulosic fibres like modal and bamboo viscose absorb moisture into the fibre, which keeps the skin surface drier and moves the sweat stain off your outer shirt and onto a $15 layer. Polyester knits like AIRism absorb almost nothing and instead spread liquid across the surface so it evaporates faster. Both mechanisms are real, and both have the same honest limit: evaporation is the cooling, and the undershirt is the plumbing, not the air conditioner. Any undershirt sold as cooling technology beyond that sentence is selling the sentence, not the shirt.
How much should an undershirt cost?
The honest range on this page runs from $3.33 a shirt in the Hanes six-pack to $43 for the winner. Packs are how the category is honestly bought: the per-shirt price inside a pack is a third to a half of the single price at the same maker. Between $15 and $45 a single buys published cloth, a collar built to stay flat, and length built to stay tucked. Past that you are buying hand feel. At $116, the price of the Tom Ford sent home here, you are buying a name attached to a garment whose entire job is never to be seen, which is the one purchase in this category that cannot pay for itself in display.
How do you stop an undershirt going yellow?
Most yellowing is not sweat itself; it is the reaction between sweat, aluminium-based antiperspirant and wash water, set by heat. The defences are boring and they work: wash whites together, warm rather than hot, treat the underarm early with an oxygen soak rather than chlorine bleach, which yellows cotton over time, and do not leave the shirt sitting damp. Synthetics yellow less and hold odour more; cotton yellows more and rinses clean longer. On the published constructions here, that trade is priced into the longevity row rather than argued about.
How this ranking stays honest
Scores follow our published methodology and are re-checked on the cadence in the byline; when a maker changes cloth, construction or price materially, the score moves and the move is noted here. Four disclosures belong on the record. First, photography: this page pictures none of its garments, because the bank holds no undershirt photography and this site does not borrow product shots it has not licensed; the frames needed, a collar hidden under an open collar, a sleeve line failing through a dress shirt, a hem still tucked at the end of a day, are on the harvest list, and the page will rather run plain than run wrong. Second, packs: every pack on this page is priced per shirt in the open, and two prices are printed in the form the evidence took, the Tom Ford at a retailer's listing of about $116 with the same line at $130 at Neiman Marcus, and the Uniqlo's cloth weight as the maker's line figure rather than a US page spec, each labelled where it stands. Third, the bamboo and modal independents are a class with a volume leader, David Archy, whose three-packs sell in quantity on marketplaces; the card here grades Mr. Davis because its maker publishes its full composition, collar blend included, and sells direct at a verifiable price, which is the standard this page holds every garment to. Fourth, every garment here was scored fresh: brand standings and sibling garments are cited as evidence where they appear, the AIRism brief at 78, the AIRism-adjacent tank at 77, the Sunspel boxer at 81 and its vest at 84, and never inherited as scores. The base layer, like the rest of the wardrobe, is graded garment by garment.
