These leggings are extremely comfortable, have a nice pocket within the back of the waistband that fits your gym card and keys. I grabbed a medium and it fit perfectly. The only reason I have 4 stars instead of 5 would be because the leggings are lighter than expected. I was expecting a deeper shade of blue, but was still very happy with the color. They stayed put during running and jumping squats, didn'thave to pull them up or unroll the waistband once. If it weren't for the color difference, I would've given 5 stars. I still recommend these leggings if you're looking for comfort and reliability!
