Hydration is a necessity while cycling. That doesn’t mean the tools for hydrating should be spartan, bland affairs. The SIGNATURE Bidon adds a flash of ASSOS styling to your hydration rituals with a 500ml size that also nestles securely into a jersey pocket for off-the-bike, hands-free transport or when you’re on bottle duty. Wide mouth provides easy filling and a more receptive target for scoops of hydration mix powder. BPA-free.
