Frame paks have separate pockets on each side of pak to organize items. All paks include water resistant zippers, fabric and all have reflective materials for visibility. These are all made in the USA and have urethane cast gripper pads where they install on the tubes to protect bike and maintain a secure fit. Each pak attaches with Velcro that will fit any tube and can be trimmed to fit. Frame paks are perfect for bike packing, day trips, commuting and can be easily removed if needed. Durable materials make the paks easy to maintain and clean.
