The SHAKEout Hexaflow Pant uses Hexa_Flow(TM) fabric with a textured inner surface that keeps air moving and resists clinging as effort picks up. The cut moves naturally with the body, so the pant works as easily for a run as it does for the rest of the day around it. What Our Gearhead(R) Experts Are Saying:"I wore these through a hard tempo effort expecting the usual clamminess by the finish, and the fabric just kept moving air instead of sticking to my legs. I never noticed them again once I changed into them for the rest of my errands after."
