Blackburn Outpost Elite Universal Seat Pack Bike Bag Mens

We developed our Outpost Elite Universal Seat Pack (USP) to work with dropper or standard seatposts, be able to carry a bevy of cargo, and stable enough to not swing around while it does. 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.
  • Waterproof: The included welded stuff bag will keep all your critical gear dry
  • Expandable: Sometimes you need more space, while other times you need less. This bag expands to accommodate both.
  • Bag Fit: Bikes come in a lot of shapes and sizes. This bag includes adjustable mounting systems to allow fitment to almost ANY bike.
  • Dropper Post Compatible: Designed to not only stabilize your seat pack, but also work with or without dropper posts. The T6061 Aluminum wing bolts to your seat rails for a rock solid mount.
