Brooks Scape Seat BagMade for gravel and adventure cycling, the Scape Seat Bag is a bike packing bag made from two separate elements: a holster and a 100% waterproof removable drybag (IP64 Certified). The holster is built from rugged materials to last, the holster bottom designed to act as a mudguard and protect the internal bag from any rear wheel contact. The dry bag easily compresses thanks to its air valve release mechanism to minimise bulk, and can be rolled smaller
