Customer Reviews

Comments: Didn't want to spend big bucks to buy in on the hype... however I love these tights. I have run in them in 30+ mph winds and -2 windchill. They are excellent. I would not run in these above 45-50 degrees as they are too warm.  They offer terrific support and feel great. Don't think I can run farther or faster just more comfortably. Have to readjust the knees on some runs. The waisting is short. Overall excellent and worth the money.  6'1" 160 I use the mediums and run 30-60 mpw 7-9 minute pace.
