Proof stands at VAUDE for waterproof and Made in Germany! The bike seatpost bag offers with a load capacity of up to 3 kg a lot of space and additional protection against splashing water and dirt. Our developers have succeeded in integrating the KLICKfix Contour adapter into the design of the bike bag so that two separate compartments with wide-opening, waterproof zippers are superimposed. This allows good organization with heavier tools stowed at the bottom and the separate stowage of Vesper or rainwear in the upper compartment. Rounding out the compact features is a cord spider located on the lid that makes stowing a wind vest, gloves or a rain jacket possible even while riding. From the use on carbon or other lightweight seatposts is discouraged or recommended to seek the advice of the wheel manufacturer. The extremely abrasion-resistant, bluesign® certified material consists of 64% recycled Econyl. The Proof Offroad M is welded waterproof in an environmentally friendly way at the company's site in Germany using high-frequency technology. The VAUDE Green Shape label stands for an environmentally friendly, functional product made from sustainable and bluesign® certified materials.
