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.

Fabric cut felt meh

Quality and feel of the shirt felt like something worse than cotton - more like a cheap poly that you might find at a discount store. Did not feel like it warrants a premium price at all. Very disappointed in the product but the customer service and return policy was very easy. Thanks and sorry it didn't work out.

Beige Undershirt

Very nice undershirt. Mostly I visible under thin clothing even in sunlight. Very comfortable to wear in all temperatures. The only downside is they are on the more expensive side. They are actually more expensive than some of the shirts I put over top of them!
