Literally. We just made the best leggings ever. The secret? TOUGH COTTON™ Technology. This cool technology uses innovative treatments to make the fabric stronger for longer by creating bonds with the cotton fibers. Fun fact: TOUGH COTTON™ Technology stands up to wear and tear up to four times better than traditional cotton knits. Result? The super-strength she needs from waist to ankle, not just the knees. Plus, just as substantial, soft and stretchy, if not more! Impressive stuff, huh? She'll agree by wearing them every day and you'll agree by washing them without worry.
