Lululemon Wunder Under Crop III Yoga Pants Lululemon created these crops to be a no-fuss tight for our yoga practice, but we just couldn't stop wearing them. The second-skin fit makes it easy to check our alignment and the calf-length leg gives us room to breathe when we're breaking a sweat. Four-way stretch Full-On Luon fabric is sweat wicking and soft against your skin. Added LYCRA fibre moves with you and stays in great shape. Tight fit is great for checking your alignment in the mirror. Wide, soft waistband is designed to eliminate muffin top. Stash your keys and gym pass in the signature waistband pocket. Full On Luon 82% Polyester, 18% Lycra Spandex.
