Designed to be discreet, especially if you like to wear your collared shirts with a couple buttons undone. Made for all-day comfort. Stay tucked and enjoy anti-odor protection 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 ProModal fabric, a highly-sustainable textile sourced from Beech Wood chips derived from the Birch Tree. The trees are sustainably farmed and our manufacturing process is “closed-loop,” meaning there is little to no waste.
Menswear experts universally praise the Invisible Undershirt
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.
