I got to loving the short-sleeve version of this T-shirt so much, I ended up picking up a couple of the long-sleeve ones when things cooled down. A super-comfortable, great-performing shirt. I have 6 of the short-sleeve and 4 of the long-sleeve ones now.

I wear this shirt casually, as well as for workouts, working hard around the house, and as a cover-up during swim meets. If for some reason it gets wet or you sweat in it, it dries very, very rapidly. So much more comfortable and functional than a cotton T-shirt. It's amazing, because you stay cool in it if it's warm or you're working hard, but you also stay warm in it when it's cool. The fabric is a very fine, dense weave, so in spite of the fact that the material is silky feeling and light weight, you stay comfortable if you're outside and it's a bit cooler and breezy. It also makes a great base-layer shirt under other, heavier apparel if it gets REALLY cool outside. If you buy your regular T-shirt size, the shirt will have a slightly loose, oversized fit, which I really like for the freedom of movement it gives you.

The shirts are VERY high quality, very durable, and require no special care. Very highy recommended. 5 stars

Very nice, comfortable and warm! Thanks. Quick shipping and better than expected. Worth every penny!!!! 5 stars

I bought about 6 of these loose fit under armor shirts in black and green. They fit great and are very comfortable. I am 6'4 and 220 and wear the large and it fits just fine and was long enough. I did buy and XL and it was too loose, so be careful about the size you choose, they're not kidding when they say loose gear. 5 stars

This shirt was great when the daily temperature starts cold and warms up during the day. It kept me warm when it was cold, and kept me cool when it was warm. 5 stars

I own 2 of these Under Armour shirts. They are not heavy enough for extreme cold weather, but is very comfortable and durable. 5 stars
