Its Flex Motion suspension system provides a close-contact design with generous freedom of movement and ventilated airflow. The padded shoulder straps feature a secure sternum strap, and the stretchy waist belt stows away for convenience. Jack Wolfskin built the Rock Surfer with waterproof, softshell-like Flex Shield fabric, abrasion- and tear-resistant Nailhead reinforcements, and hard-wearing yet lightweight Crossrip material. This daypack also features a hydration sleeve with a dust cover for your reservoir's tube, and there's a lashing option for most helmets. An integrated rain cover comes out whenever wet weather threatens your gear, and the front pocket has an organizer for bike tools. There are reflectors and an anchor loop for your own flashing light. Jack Wolfskin equipped the Rock Surfer with multiple pockets for customized organization, and side compression straps secure your load on the downhill.
