ROCKBROS AS-001 Waterproof Bicycle Rear Rack Bag 27L Black

Most rack bags rely on a separate rain cover that flaps in the wind and soaks through at the seams. The ROCKBROS AS-001 takes a different route: a fully welded 840D nylon shell with a TPU film membrane, rated IPX6, so heavy rain and road spray stay outside where they belong. The roll-top closure lets you compress the bag to match your load while keeping contents bone dry, and the quick-release hook system installs on virtually any rear rack in seconds, no tools required.

Highlights

• 27-litre capacity with roll-top closure for adjustable volume and a watertight seal
• IPX6 waterproof construction: 840D nylon with TPU film, fully welded seams
• Tool-free mounting: quick-release adjustable hooks fit rack tubes from 8 to 16 mm
• Anti-shake design with 360° rotating lower hook keeps the bag stable on rough roads
• Reflective logo enhances visibility in low light
• Detachable shoulder strap and carry handle for easy off-bike transport

In daily use

Commuting or touring, the AS-001 adapts to your load. Roll the top down three times and clip it for a compact profile, or leave it taller when you need every litre. Inside, a single mesh pocket keeps small essentials from disappearing. The mounting hooks slide along the rack rail and lock with a firm push, while the lower rotating hook grips the rack stay to prevent swaying even over potholes. When you reach your destination, release the hooks with one hand and carry the bag by its handle or shoulder strap.
