Came as advertised. Love this undershirt - comfortable, cool, dry, great fit. You'll get rid of all of your other undershirts. Really awesome shirt.

I've bought two lots of shirts and haven't been disappointed. They are a little pricier than the stuff you get at Target or Walmart, but there's a ton of added value both in quality and fit. They are longer (i.e. they don't come untucked) and fitted (they don't look like a jumbled mess under your nicely pressed dress shirt). If you are trying to make an impression, this is a serious way to up your game.

I got my dad a couple of these and he loves them! I had questions about getting the right size and they were quick and informative with their reply. Very nice customer service. My dad now only wears these undershirts and can't imagine any other.

Great fit, comfortable and don't come un-tucked. Can't think of anything else I need in an undershirt

The material and fit of underfit shirts is far better than any of the standard cotton undershirts most people have. Other manufacturers also make micromodal shirts, but the underfit ones are easily the best cut, and cheaper than most (if not all) of the other brands.

I've been wearing undershirts my whole life and it's nice to finally have found one that is actually comfortable. Love these!

It's difficult for me to call undershirt advances "technological breakthroughs". But as a guy who has to wear a dress shirt way too often and one who's dreaded wearing every other undershirt I've ever owned (for one reason or another - but I've hated every single brand), I'm going to go ahead and call these Underfit shirts a "technological breakthrough". I wore mine for the first time to a black tie gala about a week ago. Just wearing a tux is painful enough for me without the additional discomfort of a crawling undershirt under the starched outer shirt and braces (eech) . Well, over the course of that night, I became an Underfit for life guy. It stayed tucked in, kept me cooler, and didn't bunch anywhere (despite the efforts of those suspenders). Add to those features, no tags, wonderfully soft fabric, a perfect v neck (for when you can finally unbutton that tab collar late in the evening), and you have a MAJOR attitude improvement due in large part to this incredible product. Do yourselves a favor. Give your current stock of undershirts to a clothing drive and get a bunch of Underfits. You can thank me later . . .

I'm a medium slim built guy and wear generally fitted clothing, so having an undershirt that is not bulky is important. I'm very active and hate to tug my undershirt back in several times a day. Very annoying! Underfitshirts looks great, feel amazing and I never have to tug again throughout the day.
