For trail or town

Built for riders who live active lifestyles, the Quantum cycling short looks just as good off the bike as it does on. A soft, lightweight shell is complemented by the security of a drawcord waist and our sewn-in inForm BioDynamic chamois relieves hot spots for all-day comfort. From bike paths to mountain trails, you won’t want to leave home without them.
