Salomon XA Tight
Here's what other sites are saying:
The XA Tights are Salomon's most technical running pants for women. Mesh panels behind the knees allow your legs to breathe without restricting movement while you pound out trail miles one after the other. These soft nylon tights are integrated with ClimaUV to provide protection from the sun's harmful rays and Lycra Power stretch to provide controlled compression that prevents excess muscle vibration.
