The Proof 28 combines the best of both worlds! You head out on your bike for your mountain adventure needing a slim, flexible backpack. As you head up the challenging route to the summit, you need some tougher gear that can take whatever the mountain's got to give. The Proof 28 is up to the job. The solid bike & hike backpack features a flexible, motion-friendly EMP back panel. The detachable outer pocket is super practical for a GPS, maps or other items that need to be kept close at hand and you can create additional storage with a cargo net for things like your helmet, jacket or poles. Just adjust it to your needs at the moment. The classic waterproof roll closure provides quick access to the main compartment making the backpack a real multi-talent in terms of range of use, weatherproof protection and packing volume. And there are more highlights to come: The extremely abrasion-resistant, bluesign®-certified primary material consists of 64% recycled Econyl. The Proof 28 is made with fully waterproof, hf-welding with eco-friendly manufacturing at the company's headquarters in Germany.
