Ortlieb Frame-pack RC Toptube 4L

"The Frame-Pack RC Toptube 4L from Ortlieb is the perfect solution for cyclists and mountain bikers who value storage space in the bike frame without having to give up carrying water bottles. This waterproof frame bag is specially designed for full suspension mountain bikes, where the shock absorber restricts the space in the frame triangle. Thanks to the robust roll closure, which is secured with silicone rings, the bag offers reliable protection in accordance with the IP64 standard and protects your equipment from rain and splash water."
"With a volume of 4 liters, the Frame-Pack RC Toptube offers enough space for heavy equipment such as tent frames, tools or provisions. The clever positioning within the frame triangle ensures a low center of gravity, which increases riding stability. Mounting the bag is extremely simple: sturdy and strong Velcro fasteners can be variably attached to the top and seat tube so that the bag sits securely and firmly."
"Take care not to exceed the maximum load of 3 kg to avoid material breakage and risk of injury. For optimal adaptation to your bike, you can download and print out a template of the outer contour. This frame bag is unisex and is ideal for versatile outdooradventures where waterproofness and flexibility are required."
