Blackburn Outpost Elite Univesral Seat Pack and Dry Bag

Blackburn developed thr 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 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.


  • Dropper post compatible
  • Harness system securely carries inner bag for quick and easy removal
  • Scuba style air bleed valve to pack the bag as tight as you need without leaks
  • Welded seams reduce bulk, weight, and materials and improve performance
  • No swaying! Carry a large load of gear without your back swaying as you ride
  • B-Stock - This product has one or more B-Stock units available. These units can be purchased at a discount (see option select). B-Stock units were returned from other customers and may have missing or damaged packaging materials. These units are otherwise as new. The full manufacturer warranty applies.

    Totally enjoy the seat pack. I employ a dropper seatpost and the installation was a breeze.

    This pack has plenty of storage capacity and is very well built. It's allowed me to ditch my backpack for a more comfortable ride. I would recommend this product to anyone that is looking for great storage capabilities with an easy on, easy off attachment system. So I'll just say that it's not only highly functional but cosmetically appealing as well.

    The key feature for me was to have a seat pack that was easily removable. Most packs are designed to be attached to the bike so they must be loaded on the bike. I needed a pack that I could use everyday for commuting and was easy to take on-off the bike to carry in and out of the office. This has all the features of other packs but with the added convenience of being able to pack it off the bike. Other great features include the air valve to compress the bag when loading (absolutely required), and the ability to mount on a dropper post, if needed. Bag is high quality and waterproof. The mounting sling is very sturdy and easy to load/unload.
