The Olliepack Seat Bag is a must-have for any light and agile bikepacking rig. This trim 6 liter pack locks securely under your saddle with two camlock buckle straps and a rubberized velcro strap that grips the seat post.

The Olliepack Seat Bag stays locked tight under your saddle while you negotiate the shreddiest of single track. No hardware required to mount this trusty pack under your saddle with two rail buckle straps and a grippy rubberized Velcro strap for the seat post. Close the bag and compress your gear by rolling and cinching the main compartment. An external stretch mesh stash-pocket allows for quick storage of a lightweight layer. Reflective detailing on the compression straps keeps you visible on the road.
