Platypus Big Zip SL Hydration Bladder

Platypus Big Zip SL Hydration Bladder One Color 1.8L. A quick-disconnect fit on the end of the Platypus Big Zip SL Hydration Bladder's drink tube means you can easily remove the water reservoir from your pack without re-routing the drink tube, while the SlideLock closure prevents the wrist-tweaking that usually accompanies threaded closures. Platypus made this bladder with BPA-free material and added a SlimeGuard antimicrobial treatment to the inside. An angled shutoff valve helps prevent leaking after you take a swig.
