Updated review: I did not love the undershirts. They fit and they are as advertised, but too thin for my taste. Also I’m used to cotton and this feels very differently. It’s not for everyone. I... See more

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.

Wear underfit shirts everyday to work and I won't use any other under shirts any more. Underfits from here on out.
My UnderFit tees are 12-18 months old now and they are still great. They have retained their softness, elasticity, and their collars still lay flat, so the great fit and feel they had fresh out of the package is still there today. UnderFit tees are well worth the money.
They are very good undershirts and they have held up very well. I bought 4 of them that I have been using for the past 1.5 years and they are still going strong. They are thin shirts and are form fitting so that has worked well under my work shirts. I wasn't sure how long they would last since they are thin but they not have ripped or fallen apart. They are a bit pricey compared to your normal undershirts but they are a superior product.
my husband is wearing your undershirts. after many washes they start to look thinner and not as white. the shirts are also balling so they are not as smooth anymore. margriet huisman

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.
Good shirts, but expensive. Nice and tight-fitting, wears well under dress shirts.
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.
Great, comfortable, American made shirts. Price is right for the product. If only you made tank top style undershirts, you’d have a customer for life.
I like the stretchiness of the fabric, its softness and its clinginess. For my uses, I find the shirt way too long.
love the tshirts my only complaint is a small roll on the tail of the shirt as they age.
Quality has deteriorated over time vs at inception

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.
