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.

Exceptional

Love the deep V of the neck. The large fits perfectly snug and fitted after using the company’s sizing guide. Love the material also.

Worth It

Cozy, well fitting, practical. I've been buying generic undershirts for ages. I wish I had upgraded to Underfit sooner.

Undershirt review

Excellent fit and level of comfort is tops, very soft almost like not wearing anything at all

Excited

I only wish I had found underfit much earlier. Just the basic idea of their undershirt is such a useful thing for me, I should’ve realized it a long time ago, but never saw something like this before. I have many nice shirts and knitted tops, which I feel terrible having to wash after a single wear. So the undershirts will help with that. But also the crew undershirts will help some of the tops look better, or allow me to wear some tops fully unbuttoned. My first package just arrived, and the fit is exactly as promised, as well as the feeling and texture against my skin. I’m excited to try them out in the coming weeks.

Great Undershirt

Fit me and worked well under my dress shirts. Very well fitting and relatively invisible.
