The best undershirt is the one you forget you’re wearing. But don’t just take our word for it – see what the experts and our customers have to say.
I wear deep V undershirts most days with a few buttons undone. The beige is way less visible than my old white Tommy John. Size large fits perfectly.

I tried a wide range of brands before finding UnderFit. Now my drawer’s full of crew and v-necks I wear year-round. Comfortable in NYC’s freezing winters or sweltering summers. I won’t wear anything else.

I used to wear Thompson Tee, but UnderFit’s darker beige hides better under a white dress shirt. Wore it on my wedding day — looked great, felt great, and gave me the confidence to enjoy every moment.

Hands down, these are the best undershirts I have found. They are soft, comfortable, and most importantly they don’t show with my dress shirts.

USBest ever
Super light weight, nice snug fit, long tail that stays tucked in, the low cut of the v-neck allows me to where shirts with two button open! I wish these were made years ago, finally someone made the perfect v-neck undershirt!
USGreat fit
Very comfortable, invisible under my shirts. Great quality
USV neck undershirt
I bought one my son and one for myself to wear under our dress shirts. They are form fitting and very comfortable. Great product Leigh and thank you for reaching out after the delivery was made. Great experience all the way around. Greg Reillu

This was the first I had ordered and I went by your sizing chart, but it’s too small and doesn’t stay tucked in as I had hoped. I’m tempted to order one size larger just to try it so I will know, but at the price, I likely won’t. Thanks anyway.
