Wherever you're headed on your bike, you know that your gear will be dry when you get there with this Varo Messenger bag. Made without stitched seams from waterproof 420D polyester making it ideal for "all-weather" cyclists! The main compartment is a generous 15 litres, making it an ideal bike pannier for commuters. Inside, the bag has a thick, padded compartment which will accommodate a 15" laptop. Inside the bag there are two small pouches for things like a phone or a wallet. Externally the bag has two more pockets with waterproof zips on the front and on the flap too, so you can stow everything neatly. Multiple reflective detailing elements for extra visibility in low light conditions. The included adjustable shoulder strap is also detachable to prevent it from getting caught in the spokes when mounted to a luggage carrier. **Mounting system**The bag is attached to the bike's luggage carrier with Rixen and Kaul Vario hooks. When you use the bag for the first time, adjust the hooks to the luggage carrier's diameter with the screws so that afterwards you can simply click your bike pannier on the bike and take it off again every time you use it. With this system, the hooks can be adjusted to fit your luggage carrier perfectly; they will fit 6 to 16 mm tubes. The extra latch between the hooks ensures that the bag cannot be snatched off the luggage carrier. **Key Features:*** Waterproof, spacious bike pannier* Compatible with most luggage carriers including electric bikes* With snap fasteners* Reflective elements on both sides.* Additional inner compartment for a 15" laptop (36 x 28 cm).* Handy adjustable and removable shoulder strap.* Hidden RandK Vario Hooks for mounting on the luggage carrier* Dimensions: 39 x 13 x 30 cm* Capacity: 15 Litres
