Revelatory The Underfit shirts change how I wear many of my clothes. They make my profile sleeker and shirts stay in place. This and their lightness and packability make them absolute winners.

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.

The undershirts are as advertised!

I have eight pairs of UnderFit shirts have they wear incredibly well. There is a strong balance of durability, fit and quality that makes them my preferred undershirt.

I am a personal stylist and recommend this undershirt for all of my clients - in fact, I usually gift the first one to them and they end up switching out their current undershirts. Great product!

Great fitting (long) and soft. They are holding up well after more than one year of use.

Best T shirt I've ever owned without exception. I love them so much I even sleep in them!
