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.

Amazing
These are the best undershirts I've ever had. Great texture and feel, lightweight and hidden from view when worn with an open collar. Worth the price.
USZero customer service
Do not purchase from them. Unless you are absolutely sure of your size and if you like the shirt. I used their size guide and it was not correct. Contacted them multiple times and have received zero response. Tried to use on of the shirts to see. The arms rode up all day and the V in the V neck was uncomfortable. Guess I will go back to Tommy John.
USBest T Shirt
Finally a great fitting T shirt. Perfect under a light weight sweater
CAAppalling service.
Notified it was delivered when it hadn’t been. Reached out through all the channels including the “personalized” one resulting in no response at all for ages. Totally unacceptable.
USDidn’t fit and won’t respond to exchange request
Seems like a decent product but post sale customer service is extremely poor. After getting a short email response asking about the sizing when I reached out to exchange it’s been radio silence for over two weeks as I’ve tried to exchange. At this point I’m ready to dispute the charge if they won’t issue a refund and take the shirts back that are too small.
