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.

The ordering process is very straightforward and I received my orders as promised, besides the orders the shirts are fantastic and that’s why I’ve ordered three sets!!! Hoping for a Navy Blue color, not only do I use them as undershirts but I also use them as regular tshirts also!!!

Love these shirts!

I have gotten both T-shirts and underwear from Under Armor. They have been the longest-lasting and best feeling t-shirts I have ever owned. I have used them for over a decade with minor degradation. I
