If your pack gets a little dusty, just wipe it down with a damp cloth. If it's really filthy and needs a deeper cleaning, here’s what to do:
Soak it in warm or cool water with some mild soap.
Rinse it thoroughly with cool water (skip this step, and you might end up creating some suds the next time you sweat with your pack on).
Hang it up to air dry.
Your pack can go just about anywhere you go—but NOT in the washing machine. Machine-washing your pack can twist or tear the straps and fixtures, and wear away the fabric’s weatherproof coating. If you decide to go rogue and throw your pack in the wash anyway, just be aware that it voids the Got Your Bak™ warranty.
