Blackburn developed the Outpost Elite Universal Seat Pack (USP) to work with dropper or standard seatposts, be able to carry a bevy of cargo, and be stable enough to not swing around. The USP is a two part system: Part 1 is a T6061 Alloy Wing that affixes to your saddle and works with a standard or dropper post. Part 2 is a removable and waterproof dry bag. The bag has a scuba style air bleed valve to assist with compression while off the bike. The wing stays on the bike, the bag comes off and allows you to pack, compress and go ride in the snap of a few buckles.
Blackburn carefully considers what is put in each of their bags and tailors the compartments, pockets, and other features to make sure there is a perfect place for everything.
