Wearing an undershirt might feel like your first steps toward dad style—and not the cool kind. But the best undershirts for men don’t call to mind Homer Simpson or Ed Bundy. Like other uber-practical investments—think ball powder, nose hair trimmers, and calf-high dress socks—the best men’s undershirts just make sense. Whether you opt for an 100% cotton version or a moisture-wicking synthetic number, a Sopranos-style ribbed tank top or a classic crew (we’re still out on deep V-neck tees), you need a base layer that guards against excess sweat and nipple visibility.
Come the swampiest stretch of summer or the chilliest days of winter, the undershirts below are specially engineered to keep you dry, comfortable, and completely stench-free. And, since their main purpose is to sacrifice itself to save your favorite button-downs and dress shirts, most of our top picks cost less than a fancy cocktail—so you can wear and wash them to death, and then replace ‘em semi-regularly without a care in the world. Oh yeah, and all of ’em are tagless, because no one needs to spend all day trying to ignore a tiny rectangular piece of fabric. Without further ado: the 17 best undershirts for men to tuck in pronto.
The Best Buy-in-Bulk Undershirt
Uniqlo stays doing what Uniqlo does best: delivering tech-driven, well-designed, perfect-fitting basics at no-brainer prices. Their Airism tees are crafted from a smooth and breathable polyester blend that’s anti-microbial, deodorizing, and will keep your underarms feeling cooler than the Fonz in the face of turgid, muggy July days. At just $15 a pop, you can afford to buy enough for every day of the workweek—plus a few extra for the gym and hikes and whatever else the summer brings your way.
The Best Buy-in-Bulk Winter Undershirt
Uniqlo’s famed Heattech garments are designed to keep your body nice and toasty all winter long. This particular tee clocks in on the warmer end of the range and is cut from a silky smooth fabric that’s been brushed on the inside for maximum softness.
The Best Soft-as-a-Kitten Undershirt
If you’ve ever bought underwear using a podcast discount code, then you’re already familiar with modal fabrics. Fashioned from beech trees, the fabric is purportedly [extremely Marc Maron voice] twice as soft as cotton, naturally antibacterial, and fully biodegradable. These tees from Tani take those claims another step further still: they’re crafted from Micro Modal Air, the finest form of the stuff around, which the brand says is thinner, stronger and softer than silk. We have no way of proving the science behind those assertions, but we can at least say anecdotally that these shirts are so soft and light they nearly feel like wearing nothing at all, and they seem to do a bang-up job of keeping summer-induced stink at bay. Now, back to the pod.
The Best Classic Cotton Undershirt
In the event that you really just want to keep things old-school, well, Calvin Klein still makes the very best 100% cotton undershirts in the business. They’re lightweight, fit well, and are polished enough to wear around casually as a regular tee. If you’re lucky enough to land on the drier, less-malodorous end of the scale, and just need a easy, classic, regular cotton base layer to get you through the week, this is the three-pack for you.
The Best Undershirt for Serious Cold Weather
Super warm, unexpectedly soft, and engineered with strategic paneling and stitching for superior comfort, this merino wool base layer is dense enough to get you through the toughest winters. Don’t worry, though: it won’t feel like you’re wearing a wool sweater beneath your button-up—it’s slim enough to keep a low profile and ensure you don’t overheat indoors.
The Best Silky, Slimming Undershirt
Tommy John’s aptly-named undershirt doesn’t just fit like a second skin—after a few wears, it molds to your body, hugging its every contour with more gusto than your most affectionate aunt. Its soft, silky finish won’t pill no matter how many times you put it through the ringer (or the washing machine, for that matter), and in a micromodal blend—with a touch of spandex for good measure—it’s a solid Spanx alternative for anyone trying to hide a growing gut.
The Best Gains-Enhancing Undershirt
Far be it from us to unilaterally declare anything objectively sexy, but if we had to pick a tank that fits the descriptor, 2(X)IST’s might just be the one. The brand’s distinct square-cut style will make your upper body look exponentially more defined, no matter how long it’s been since you last saw the inside of a squat rack.
