Altura Vortex Waterproof Dropper 7L Seatpack
Stable. Waterproof. Dropper-Compatible.
The Altura Vortex Waterproof Dropper 7L Seatpack is designed for riders who demand performance, waterproof protection, and compatibility with dropper posts. Perfect for gravel, MTB, and bikepacking adventures, this rugged seatpack delivers a stable ride with a secure yet easily removable Rixen & Kaul Klickfix mounting system, engineered specifically for dropper post use.
Made from tough waterproof fabric with welded seams, this seatpack keeps your gear protected from rain and trail spray. The roll-top closure ensures a watertight seal (when rolled 3 times), while the external bungee cord system offers flexible storage for quick-access items or the Altura Anywhere Drybags for extra capacity.
With a 7L capacity and a maximum load (including bag) of 2kg, it's ideal for carrying clothing, tools, and supplies on your next off-road ride or multi-day adventure.
Note: While waterproof, the seatpack is not submersible. For valuable electronics, we recommend using a dry bag inside the main compartment.
