If your idea of a good time includes shredding singletrack or ripping rougher terrain on bikepacking adventures, the Olliepack Seat Bag is your new back-of-bike best friend! A great addition to any off-road rig, the Olliepack Seat Bag offers a straightforward, roll-top closure providing added water resistance as well as variable capacity to suit your carrying needs throughout the roughest of rides. No rack or hardware needed to lock this bag tight under the saddle and out of the way enough to get your bum behind the saddle while negotiating steep descents or tight trails. Combine the Olliepack Seat Bag with a Zeitgeist Pack, Hold Fast Half Frame Bag, a couple of Gibby Stem Bags and the Moxie Top Tube Bag for a perfect, lightweight rack free overnight setup. This seat bag stays snug and stable on the most rugged terrain with the trusty help of secure saddle rail buckle straps and a wide, grippy seat post velcro strap. Close the bag and compress your gear by rolling and cinching the main compartment. Once the main hatch is closed, an external power mesh stash-pocket allows for quick storage of a lightweight layer, wrappers and more. Reflective detailing on the compression straps keeps you visible on the road. The Olliepack Seat Bag is made from recycled polyester and contains roughly 10 recycled bottles rescued from polluted rivers.
