USWE’s No Funky Stuff™ - Hydration Bladders are disposable and help prevent bacteria growth in used bladders. Toss the bladder in the recycling bin before it gets funky and grab a fresh refill. The bladders are durable, inexpensive and BPA-free.
Bladders filled with water only can be reused a number of times, just clean with fresh water between uses.
Bladders filled with liquids other than water should be replaced to prevent bacterial growth.
Get fresh bladders and clean hydration for a very reasonable price.
