Just received my second purchase. Originally bought two about 1 yr ago. I really like the fit, comfort and warmth these provide. They are very thin and seem a little delicate, so I hand wash and lightly tumble dry (not much is needed). Some of the stitching is starting to unravel/fray around the collar, but it does not stop me from wearing them often. I'm 6'2 and 225 lbs and the XL is perfectly snug (not too tight) and plenty long.

They are always under another shirt (polo, t-shirt or dress shirt) and can become warm when it 65-70 deg or higher. I wear them under dress shirts in the office and I'm just fine, but a little movement/activity will really warm you up. Must be the tight fit stops the breeze from reaching your skin. They are great under a polo/t-shirt in the SF Bay Area with average 50-65 deg days.

Buy the right size and it will fit as compression. It's a good shirt. Nike or under armor is better

Perhaps, if feeling generous and assuming a very loose definition or compression, this could be defined as such. I originally ordered a medium. It was much too large. Returning it was simple and easy. I then ordered a small... still loose, nothing compression to it at all. Do not buy this product if you are looking for compression features. If you are looking for a comfortable base layer, go for it.

Awesome shirt. I got into some of my older dress shirts and the compliments make me want to eat less and make the reduction happen!!!

Performs well but when I ordered the shirt the pic and description were that of a normal looking t shirt not the tight wife beater that it really is.
