Very soft, comfortable, and warm.
You can get them in compression or fitted, depending on your preference.
I use them as my base layer (top and bottom) and love them. Switched from regular wool and polyester base layers.
+1 for Under Armour
All I ever need to wear on a normal day is my under armour cold gear mock and a t-shirt and I'm good.Also really versatile, I've used it to play football, run, and just as a normal day layering piece.
So I broke down and bought a set of mid weight Smartwool pants and crew shirt. I've always worn cold gear for soccer games, hiking and mtn biking, as well as snowboarding. I tend to freeze on the mtn and after talking to a handful of people who've sworn by smartwool, I decided to give it a go. I think UA is great, but I also think it's probably trapping the sweat and making me freeze as soon as my body temp drops. We'll see....
