I love these. I had an older pair that lasted about 3 yrs with somewhat sporadic wear in the gym, but I started running outdoors 4-5 days/wk about 6 months ago. I went down a size and was forced to get a new pair. They are my go-to running tights for all weather, all terrain, all distances, short runs, easy runs, hard runs, long runs, etc. I prefer them over shorts, and I only need to switch them out for pants when it's below freezing. I sort of wish they had a zipper pocket large enough for my cell phone, but it's a small sacrifice to make. Also, I have owned both these Nike capris and a similar version made by RRS. I prefer these because they fit like a glove and I've never had any chafing issues; the RRS brand doesn't fit me as well and unfortunately chafes like whoa. I only use those for casual activities like kayaking, low-intensity hiking, and watching my boyfriend's cycling races.
