Incredible Fit and Feel
Best. Undershirt. Ever. Really, you can't do any better than this. This undershirt may not change your life, but it will change how you feel and look.

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.

I love these undershirts and they are so worth the cost

I ordered 4 V-neck undershirts to replace a scoop necked undershirt. The V was unsatisfactory, and UnderFit promptly accepted my return and refunded my payment.

Hey Mike, We're sorry the v-neck wasn't deep enough for ya. We're deepening the V on our summer manufacturing runs (July), so we'd love to see ya again if you're interested. Thank you

Great product and price. Simple purchase process exceeded all of my expectations.

Great undershirts. I've tried them all online and in stores, At least 12 different companies. These are by far the best if you want a light weight, soft, breathable, fitted undershirt that won't come untucked. If you're not used to a fitted shirt these may feel about 1/2 size small to you. So you might want to select one size larger than normal.. I like the tighter fit as the shirt stays in place all day long. In a dress shirt, I wear a 16.5" neck 34" sleeve. Suit/sport coat 44 athletic cut. I buy the Large Underfit shirts and think they are a perfect fit.

Very happy with Underfit!

I've purchased many different brands for my husband.... he could never find a great fit. He is 6'4 with broad shoulders and lean waist. Most of them were too bulky and one that wasn't rode up on his sleeve. These are lightweight, fit to the body and not too tight. Perfect. After trying UnderFit we purchased 14 more and turned all the others into cleaning rags!!! No kidding.
