Underfit shirts saved me from worry
Underfit shirts have pretty singlehandedly solved my worry that I’d never find a tall enough under shirt. But it’s comfort makes it even better

UnderFit undershirts are cut longer and lightly hug your hips and below, to stay tucked in all day. Our fabric is ideal for undershirts due to its exceptional softness, advanced moisture absorption, odor resistance and superb breathability. If you want to remain less comfortable in your run-of-the-mill undershirt, by all means, DON’T buy an UnderFit.

Great fit, unbelievably comfortable.

Long undershirts don’t come cheap, but you get what you pay for. Very comfortable, feel great all day, longer than I need—and I’m 6’4”!

Very expensive and very worth it. The material is thin but flexible...and the length is long so nothing gets bunched up. Best undershirt I've ever worn.
