An adjustable hook on the bottom keeps him firmly in place. The handy roll closure prevents rainwater from entering the bag. In the spacious main compartment there is an inner compartment for smaller valuables. The back of the bag is reinforced with wear-resistant plastic, making it shock and impact resistant. With the detachable shoulder strap you can easily take the Aqua Back with you when you continue on foot. If you leave the bag on your bike, secure it with a steel wire thanks to the Lock Loop system. This reduces the risk of theft.
