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 when less carrying space is needed. The daisy chain allows attachment of modular bags, and a loop is included to attach a rear light. Made from waterproof material to be prepared for any ride, regardless of conditions.
