This product does not include reservoir-image is to show access. Kokatat's Tributary Rear Pocket (without Hydration System) is an add-on pocket for the back of a PFD (this is the older discontinued style with zippered side and top loading pockets).

The Tributary attaches to your PFD with velcro tabs that fasten to the shoulder adjustment sliders on the back and side adjustment straps of most sea kayaking PFD's (not just the Kokatat brand pfd's).

Add your own hydration system or use the pocket as a place to store some emergency items (but you'll need to take your PFD off to get to items in the top loading pocket).

Colors: Red
