I run and I am in the gym doing various types of workouts several days a week. I have worn every brand of tight known to woman. I'd had an injury and was getting back to the gym and decided to try a few tights with pockets since none of mine had pockets. I looked at all my usual big brands and decided to go with these because of the price and the reviews were so good. After ordering one pair and wearing them to a couple of different workouts (Total Body conditioning (which is a weight lifting style), and cardio kickboxing which has tons of jumping jacks (my ultimate test for comfort and staying up and in place). I was SOLD. I went right back and bought several other colors. I will literally wash my clothes the night before class if there aren't a pair of these clean. I may as well throw the rest of my tights away because I only move them around to find a pair of these. I love these tights and the price is awesome. Also, I get sad when I think about the old days when I used to have to wear a tight without a pockets!
