Here's what other sites are saying:
Layer the CW-X Men's Element X Pants over your tights on windy days, or wear these pants on their own for your wet spring and fall runs. With windproof, water-resistant fabric, these pants have you covered. Anatomically articulated knees give you plenty of room to move as you bound down the trail, and bottom zippers make the Element X Pants easy to pull off after a warm-up lap.
