Like its namesake (trucker lingo for a speeding big rig) the Gearjammer™ helps haul all the necessary items for overnight bikepacking trips and randonneur adventures alike. Lightweight, waterproof materials and bomb-proof construction create a light yet durable pack with all the features needed to securely store gear from your seat post. The Gearjammer™ seat bag has stiffened side panels and a plastic frame sheet that keep the pack stable and positioned away from your legs. This bag will not wag; the Gearjammer™ is one of the most stable seat bags on the market.
