Excellent pants I was a bit skeptical about getting running tights because I'm not a fan of form fitting clothing, but these are actually the perfect fit (close fitting, but not snug like normal skin-hugging tights). The mixture of windstopper and regular fabric is an excellent feature and lets you air out while protecting your exposed thighs. I've worn them in 40+ degree runs and have been warm, but not too bad, and ran today when it was 15 degrees with 30 mph winds and they did great. I'm a fan. January 7, 2014
Running Pant These pants fit well and protect against the elements, I have run in rain and snow and stayed dry and warmish.Not fond of the drawstring material, it is springy so it doesn't really ever get tight. December 19, 2012
