These black Balmain zip detail sweatpants have been constructed from sumptuously soft cotton. Hosting an elasticated waist with drawcords, biker-inspired ribbed detail above the knee, front zipped pockets and back zipped pockets. Take on the bench press in these Balmain track pants. Or maybe you’re more of a Swiss ball kinda guy? In fact, these bad boys are too good to be confined to a sweaty gym.
