this is the second pair of cw-x tights that i get. they are more on the pricey side, at least for me, but i've found them totally worth it. i'm training for a marathon this year, so i run a lot during the week and on the weekends, and i alternate between my two pairs. they are holding up niceley and they really provide great support. i notice that i feel way more safe and supported running in these than running with running shorts. i've even improved my marks! anyway, as the weather gets warmer, i find them a bit too warm, even though these are supposed to be "ventilator". but i would recommend them without any doubt to anyone who is or is thinking to get serious about running. it's a great investment. along with my running shoes i think this is the second most important item in my running gear.
