It's important to consider these instructions carefully. While we stand behind the quality of our bags, not adhering to these instructions will void our warranty against manufacturing & defects. - Take care while packing. Sharp and pointy objects should be covered or protected agains the pack fabric as much as possible to avoid punctures. While our pack pockets are meant to be expandable, it is possible to overstuff them. Don't force zippers closed or excessively yank on attachment points. - Hand wash only. Spot wash stains and dirt as needed. Do not bleach, dry clean, or launder. Use a mild soap when necessary. Hang or lay flat to dry. Do not tumble dry. - Clean the bladder with dish soap and warm water. A bottle brush can help with stubborn areas. Thoroughly rinse so there is no detergent left behind, and allow to air dry. Regularly emptying the bladder and allowing it to dry after each ride will reduce the need for regular washing. - Flavored drinks and powdered drink mix may stain the bladder or otherwise cause a long-lasting change in flavor. Do so at your own risk.
