I chose these because I had heard they dont give you that plumbers crack, and its true! Squat, stretch, run, jump -- do whatever! And if your sizing is right.. these pants will stay on you without it ever distracting you. Great overall.. and secure pockets if you are the business-on-the-go type to carry your phone everywhere. True to size to give you versatility such asc large legs and seat, stuffing your pockets or wearing shorts underneath. You can go a size down if you want them to hug your legs a little more and brag about your quads!
