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.

Features

Dropper Compatible - Designed to not only stabilize your seatpack, but also work with or without dropper posts. The t6061 aluminum wing bolts to your seat rails for a rock solid mount. Get the perfect cargo fit for the roughest trails.

Bleed Valve - The waterproof dry bag features a scuba style air bleed valve so that you can pack your bag as tight as you need, and not have to worry about leaks.

Welded Seam Construction - Welded seams not only reduce bulk, weight and materials, they improve performance by eliminating the needle hole, a potential area for saturation and leakage. Welded seams also create a clean finish on both the interior and exterior of the bag.

No Sway - Able to carry a bevy of cargo, and stable enough to not swing around while it does.

Harness System - This bag features a system that is comprised of an outer "Harness" that securely carries an inner bag. The inner bag can quickly and easily be removed from harness, without having to detach the harness from the bike. The advantage is that is saves time, is more secure and allows you to carry odd/oversized items or use your favorite aftermarket bags.
