HydraPak 3.1L-3.5L Short Profile Bladder

The HydraPak 3.1L-3.5L Short Profile Bladder was the Hydration system that the
PIG 3L SP Hydration Carrier was built around. This Hydration Bladder features an Internal Baffle for a more compact profile while reducing sloshing of its contents. The Baffle can be separated by hand and reapplied as needed. The actual capacity of the Bladder with the Baffle engaged is 3.1L and increases to 3.5L when the Baffle is separated. The wide slide-top opening allows for fast filling and secure seal. The HydraPak 3.1L-3.5L Short Profile Bladder comes complete with PNP Connectors, Hydrafusion Tubes (Coyote), Bite Valve (Coyote) & Dust Cover.

    Super fast shipping and absolutely love the products I recieved. Installed it on my plate carrier the night I got it. Never ordered pig product and was very impressed with the quality. Really like the bladder. Easy to clean and dry out. Have not figured out to take apart the mouth piece to clean yet.
