We did it! We had Iron Knees® down pat for boys’ pants, so we jumped for joy — and you will, too — with our latest invention: strong Iron Knees® patches in cute leggings for girls that don’t pucker or pull and are invisible from the outside, too! The secret lies in all-way stretch patches added to the knees of our leggings, already made with twice as much spandex as the others. The result? Super-soft, stretchy and strong cotton-jersey leggings with no baggy knees, no show-through and a fit that bounces back wash after wash.
