Great All Around Shirt
I've been wearing this shirt on hikes and am a big fan. It does a great job of wicking away sweat. I'm 6 feet 175 lbs and purchased a medium and am happy with the fit. A large would have been too baggy. ENJOY.

Awesome All-Around Shirt
This is a great choice for just about anything you want to do! It's incredibly comfortable and fits great. At 6' and 175 lbs. the large is perfect. It's so lightweight it makes a great layering piece under heavier shirts. And it looks really good by itself too. I bought the black and couldn't be happier with it!

All I want to wear
The UA 'Catalyst' line is incredible. They are the most comfortable shirts I have ever worn. I want to wear them all the time; it looks great by itself and feels great as a layer. I have two of these shirts and plan on buying more.
