Been wearing them since my backpacking days years ago. Beats the heck out of the 100% cotton "T's" for wicking sweat and drying fast. The cheaper poly's tend to pull easy and pill up if put in the dryer. I always wash in cold water and dry on a hanger. Do not put them in the dryer. The best poly shirts I have found are the Royal Robbins version and the ones that have a 60% poly 40% cotton blend. The Under Armor long sleeves offer a good next to skin layer in winter conditions. The backpackers sorted all this out years ago.

 

Love the stuff!!

 

I am also a fan. I also wear a skull cap they make under my helmet, no more do rags.

 

I wear the compression style longsleeve top and bottoms for hunting. They wick the sweat away like nobody's business. After a half mile hike in the woods, I'm soaked with sweat, but these things really do a great job at pulling the sweat away from your body and within a half an hour in the stand, they're dry. They breath extremely well. You wont be dissappointed in them.

 

I like the stuff, but not because I think it "wicks" anything. It provides some support and also cuts down on friction. There is a reason one is not suppose to wear cotton while hiking or hunting during the winter and that is because when wet it loses most of it's insulating properties. To test this try putting a damp sheet or t-shirt on next time you get a sunburn. If you put your hand over the burn you can actually feel the heat leaving your skin. Wool or polyester is better at keeping it's insulting properties while wet. Just my opinion, but I can put 2 and 2 together and think this entire wicking thing is just BS marketing .

I wear underarmor while playing hockey because it is more comfortable under the gear then cotton, but I can tell you it ends up just as soaked with sweat as a cotton t-shirt. I tried wearing Underarmor while riding on a long trip and from my results I would guess under jeans it is not wicking very well at all and tends to retain moisture. I will leave the details of my experience to your imagination.

 

This might qualify as TMI (Too much info). LOL

 

I got the compression stuff to wear under a riding suit for a 3,300 mile trip through the South this summer. It was great. Not only did it keep me cool, the compression made long-mileage days easy. I'd rinse it out when I stopped for the night and it would be dry by morning. Too much effort for local riding, but great on a long haul.

 

Works fantastic at keeping you dry. Plus the collar won't stretch with the wind buffering. However, I've had mine for a few months here in the horribly humid South and they are starting to smell...(yes, I wash them every week)

 

The knock-off UnderArmor stuff, like Starter brand, works just as well as the real thing for a fraction of the price. Polyester is polyester. I wear it everday under my vest at work. It is a great improvement over a cotton t-shirt....

 

I got mine on and am freezing right now. Cool.
