Lightweight, moisture-wicking base-layer, constructed using odor-control fabric; ideal as a lightweight base layer during aerobic activities. These lightweight bottoms are engineered for optimal moisture management during stop-and-go activities. Moisture is wicked across the garment via hydrophobic Phasic™ yarns that broadly disperse moisture, aiding temperature regulation by increasing evaporation and speeding dry-time. Encapsulated silver ion fibers provide long-lasting odor control.

very nice
January 25, 2012

These bottoms are great if you just want a little bit of extra warmth. They only weigh 93.5 grams (size S) and they take up very little space. They fit snugly, as they should. The excellent Phasic SL material is almost like silk in comfort (but of course wicks much better) and dries quickly after washing. It's easy to slide pants over these because they are smooth on the outside. And they stay put when wearing all day long. They are thin enough to put socks over, and they are stretchy enough to put over socks.
