The F6 PRO is equipped with the latest version of the No Dancing Monkey Technology. It's an incredibly comfortable pack that offers outstanding fit and function even in the hardest terrain. This is the Enduro/Freeride pack - you'll love it in action. PRODUCT CARE We recommend wiping your pack with a damp cloth to remove dirt. If the pack is extremely dirty and needs a deeper cleaning, soak it in cool or warm water with a very mild soap. Rinse the pack thoroughly with cool water. If soap residue remains in the fabric, it may create suds if exposed to water or sweat. DO NOT wash your pack in a washing machine. Machine washing may damage the pack or affect the integrity of the fabric and fasteners, and will void the USWE Guarantee.
