text: Camelback is a trusted name in the hydration game. I have had a few back pack type hydration systems and Camelback is my go to. I needed to replace the bladder in my Mule. The Mule cleaned up really well in my clothes washer. This bladder fit the bill and it even had the toggle shut off which the old one didn’t have. The old one didn’t have the insulated sleeve on the tube like the new one either. Highly recommended 5 star rating.
