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.

A+++++ Customer Service

I ordered three shirts from UnderFit, and while they didn’t end up being the right fit for me, the customer service blew me away! I reached out about a return, and Leigh from UnderFit responded immediately with a quick, no-hassle solution that worked out perfectly. Seriously—top-notch service! If you're thinking about ordering, go for it. You're in excellent hands!

Hands down best undershirt I have worn to date

This undershirt delivers on its promise of invisibility under outer layers, thanks to its beige color. The fit is true to size, and the soft, breathable TENCEL™ fabric enhances comfort. The lightweight material prevents overheating while absorbing sweat and minimizing odors. Additionally, the longer length ensures it stays tucked throughout the day. The only aspect that could be improved is the sleeve length—shorter sleeves would offer a better fit, especially when layering under short-sleeved shirts. Overall, it's a well-designed undershirt that prioritizes comfort and discreet wear.

Love It

I am enjoying it although I’m reluctant to throw it in the dryer and just hang dry it as I’m afraid it will shrink or not last as long. It does take a while to ship, 2 weeks and wasn’t sure why so long.

Tee's are terrific as advertised. Cost, import duties, delivery makes this very unreachable for most in Canada. Require a more cost effective approach to deal with Canadian masses. CT
