Bikepacking Seat Pack - 7.5L

Ortlieb Bikepacking Seat Pack (7.5L) is a waterproof bikepacking saddle bag built for riders who want fast on/off convenience without sacrificing stability on rough roads and trails.

Its Seat-Lock attachment system mounts quickly and removes just as easily, staying secure while riding and leaving the bike clean when the bag comes off. Inside, reinforcement and multiple compression points keep the load tight to reduce sway, while the roll-top closure and rugged laminated fabric protect gear from weather and road spray. An included adapter expands compatibility for select dropper-post setups, making this a versatile option for modern gravel and mountain bikes.
