Special Occasion Undershirts
Outstanding material and comfortable, long lasting shirts. I wish they were just a bit more affordable so I could use them for daily wear instead of special occasions.

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.

A good undershirt especially when wearing a white shirt
By UnderFit CustomerJoe D.
I love the fit and feel of these shirts. Do they cost more than a department store under shirt? Yes. Are they worth the premium price? Absolutely. I’ve had several for nearly a year now and they feel just as good as the first day I got them. No bacon collar. They keep their shape all over. The shirts are also long enough to stay tucked in. One of the best things about the Underfit shirt is that it can be laundered normally, unlike some competitors. I have tossed every one of my former under shirts into the car wash rag bag. The only negative thing I would have to say is that the shirts do pill a bit. Not a big deal to me but worth mentioning. I should also mention that the customer service is out of this world. The owner of Underfit is passionate about the company and it shows.

Shirts are fantastic. Exceeded expectations..

Form-fitting cut and material keep dress shirts from poofing out at waist. Have worn well 1+ year in. Will buy again when it’s time to replace.

My husband is a dialysis patient. The T-shirt’s fit beautifully and also hold his port secure. He is usually an XXL tall and the largest size fits him and stays tucked in. He wears them every day-literally all seasons and I have just bought the second 10pack because a couple of the original 10pack are just now starting to get shabby. Great material, great design, wonderful customer service.
