The Seatpacker is a reliable, innovative seat bag system designed to handle any bikepacking adventure without tail wag. Featuring a solid aluminum hanger that attaches to your saddle rails and seat post, this 100% waterproof bag comes in 9L or 15L sizes.

The flexible seat post mount adjusts to standard and aero posts without damaging them, and it's compatible with dropper posts. With a lean, aerodynamic shape that prevents thigh rubbing, rugged construction, and external netting for extra gear, the Seatpacker provides ample storage capacity with maximum stability.
