Jack Wolfskin Rock Surfer 18.5 Rucksack Black

Check your brakes, helmet on and you're back in the saddle at last. Your water bottle, tool kit and rain Jacket are already packed and ready to go in the Rock Surfer 18.5 Rucksack. This small day pack is specially designed for biking with a minimal amount of kit. Jack Wolfskin's Flex Motion suspension System is purpose–built for fast–paced cross–country tracks and mountain trails. So the pack sits firmly against your body and is highly flexible, right down to the four contact zones. The gaps between the back pads help to cool your back with a constant flow of fresh air, and the elasticated Flex Shield fabric either side of the zips makes them easier to operate when the pack is stuffed full.
