Outpost Seat Pack & Dry Bag

Not quite falling into the category of pannier or backpack, the Blackburn Outpost Seat Pack & Dry Bag sits in a class of its own, relying on a functional seatpost-mount design that includes a waterproof dry bag to keep your bikepacking or commuting essentials safe from the elements. Daisy chain loops along the outside of the bag help you corral extra lights and other gear while the entire design sits cleanly below your saddle and out of the way of your frame. Please note that the Outpost Seat Pack is not recommended for use with carbon seatposts.
