Feels like it’s barely there. Am amazing second but better looking layer of skin.

These compression tights fit well and most likely will resist most moisture. They also seem durable and should hold up for endurance events like cold-weather races--maybe even triathlons. However, I haven't had a chance to test them in extreme cold (below -5 degrees C) and, judging from how they feel in moderate cold (+5 C), I'm not sure they're up to the challenge. But for the price, they're more than good enough if you aren't expecting them as a lifeline in super-cold climates. And they look good too!
