A waterproof solution for the modern cyclist: Axiom’s all new waterproof Hydracore system allows us to use the time-tested construction methods that have earned us industry-wide respect for quality, serviceability and functionality, all while adding a new level of waterproofness. Hydracore is the perfect solution for cyclists who want a premium pannier that they can trust to keep their belongings dry and organized in all conditions. The combination of a water resistant outer layer and a waterproof inner liner allows us to offer features traditionally found on non-waterproof bags that require rain covers. Your electronics, documents, and work clothes are valuable to you, so keep them protected and easy to access with Hydracore.
