The compression fabric used for teir leggings and crops takes on a second-skin-like fit. At first, it will feel really firm but the material will relax to your body shape and won’t bunch, sag or roll down during your workout. Just like a great pair of skinny jeans, you might need to jiggle into them but once you are in them they will fit like a glove and you’ll never want to take them off! (They don’t recommend this for a couple of reasons though you know, like showering and personal hygiene stuff. But whatever, they don’t judge. You do you!)
