If you want to remain less comfortable in your run-of-the-mill undershirt, by all means, DON’T buy an UnderFit.

I’ve been wearing Underfit shirts for years, and nothing else compares. The quality and comfort are unbeatable, and every time I wear one I feel confident and sharp. They’re an absolute essential in my wardrobe—I won’t go without them.

Great shirts. Perfect fit. Tried a couple of other brands once when Underfit was sold out of my size. Never again. UnderFit is the only choice for me now.

Just placed my 3rd order and will place 4th soon. I’ve been an avid undershirt wearer for 25+ years and these are the best ever. Slimming but not restricting, form fitting but not tight. Just perfect.

I’ve been wearing these for years. They fit great. Comfortable. They don’t come untucked. They protect your shirts. They last a long time. Customer service is excellent too. I was short a few shirts on my last order and the owner of the company fixed it himself in less than a day. They’re a bit expensive, but totally worth it.

This t-shirt does its job by not showing, fits snugly, keeps me cool, and protects my dress shirts. In comparison cotton t-shirts are like another layer of clothing and create bunch up bulges.

Simply the best! While the shirts do last a long time, I like to replace them annually to get that new shirt feeling. I've tried other shirts, but I came back and will not leave again!

I was so happy to know that this brand was renewed. I was a big fan of the previous company Ribbed Tee's product and stoked to find out that UnderFit resurrected it. I have bought several of these and will be buying more to ensure I've got enough to last a lifetime.

I have purchased various forms of performance Undershirts over the past 13 years or so. (I can't begin to imagine how much I've spent on ones that I didn't like). I never found a "perfect" one until Underfit. It's the first one where the sleeves don't stick out when I'm wearing it under a short sleeve t-shirt, it is long enough to stay tucked in, absorbs sweat well in the Arizona heat and most importantly they last. I have all the original ones I purchased over a year ago and have worn every week. They are in great shape still. Do yourself a favor, spend the money on these, it's a worthwhile investment in your comfort.
