I absolutely love these leggings pants from the feel of the fabric, fit, color and functionality! I’ve used them for running, and working out. For my run and workout they stayed in place and I didn’t have that uncomfortable sweaty feeling because they were definitely breathable. And for running around errands throughout your day the pockets are a plus so you can have your phone. As for working out I would say that your phone may stay inside your pocket if it’s nothing high intensity, I wouldn’t recommend putting your phone in the pockets for running though. I tested them out with few stretches and they have good flexibility. They’re also definitely squat proof, not see through at all. I definitely recommend this box, they’re great quality for their price, it can definitely compare to higher priced brand name leggings!
