"I like the fact that you designed your jeans without the cheap hotel syndrome (no ballroom)," wrote John P. from Ohio. Good point, John - so now we call them Ballroom® Jeans. And give them a 100% cotton flannel lining that keeps you warm when you're working out in the cold. Our flannel lined jeans are cut on the easy side, and built with a hidden Crouch Gusset® that lets you bend, stoop or squat in comfort.
