Our crew neck is perfect if you like to wear with your shirts fully buttoned up. Stay tucked and avoid embarrassing sweat stains with an incredibly soft, breathable feel.
We back all of our undershirts with a 100-day guarantee. We’re so confident in them that in the unlikely event that the collar ‘bacon necks’ or a seam breaks, don’t sweat it! We’ll gladly replace it with a new one.
The moment you put on an UnderFit undershirt, you’ll notice a huge difference compared to other undershirts you’re used to wearing. To design the best men’s undershirts, we analyzed everything we hated about traditional, poorly-made basics. That’s why we set out to make an undershirt that:
You don’t need a six-pack to rock an UnderFit undershirt. They say clothes make the man. At UnderFit, we know confidence starts underneath.
You’ll never want to take this undershirt off! Our undershirts are made from TENCEL™ fabric, a highly-sustainable textile sourced from wood chips. The trees are sustainably farmed and our manufacturing process is “closed-loop,” meaning there is little to no waste.
Hear it straight from the professionals
Gotta tell you, it’s a very nice product. Good fit, good feel, good price. Comparatively, the UnderFit fits and feels very close (or as nice as) to the more expensive micromodal/lycra undershirts.
No rising, No billowing. We managed to get through a whole day without a single untuck from under our made-to-measure shirts.
The problem with most undershirts is that they’re just T-shirts. UnderFit’s shirts are made from lightweight yet durable fabrics with a touch of stretch and are designed to be worn under your shirts.
All of our undershirts are backed by a 100-day guarantee. Don’t love it? Contact us and we’ll make it right.

The quality of the product is great, feels nice to wear. The only thing for me would be if the v-neck was not so low.
The undshirts are a great fit and the most comfortable that I have ever worn! And the shipping is very quick! Thanks So Much
Great, underfit tee shirts are all I wear, probably about 5/6 years now. So soft and I love the fit, thank you, Denny
Excellent. My only complaint is you can’t keep them in stock!
The shirts fit me perfectly. They are very soft, form fitting, and seem to be made of high quality. The beige matches my skin tone well. I also like the fact that they are long enough to not become untucked. Will buy more.
