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.
