More Than Your Average Undershirt

frequently asked questions

How do your undershirts fit?

Our undershirts are designed to be close-fitting, hugging your body without being too restrictive or uncomfortable. We believe an undershirt’s fit should be the perfect balance of snug and comfortable (without adding any l.b.’s to your appearance.

What's the difference between an UnderFit Undershirt and a regular T-shirt?

Our Undershirts are made with a lighter, thinner fabric designed for softness, durability, and comfort above all else. Our customers report feeling more confident wearing their UnderFit shirt.

Do your undershirts help sweating?

UnderFit undershirts cool you down and prevent pit stains. We use a proprietary blend of Super Modal and Lycra to deliver the most breathable, sweat wicking undershirt that’s still comfortable. Our ultra-thin, super soft layer wicks away sweat from your top layer shirt actually keeping you cool and dryer than you would be without it.

How many undershirts should I have?

The best recommendation is to have between 3 and 4 weeks worth of undershirts in total. This is usually best managed with a range of colors and neck styles (crew vs. v-neck) so you always have fresh undershirts even during large wash cycles.

reviews from the pros

“No rising, No billowing. We managed to get through a whole day without a single untuck from under our made-to-measure shirts.”

THE GENTS STAFF
Gents Among Men

“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 that are priced in the $30+ range.”

Tug
The UnderShirt Guy

“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.”

“If there is a better purpose-built undershirt out there, we have yet to find it.”
