When you're completely surrounded by water, it can be easy to forget to take a drink every now and then. Stay hydrated while you're paddling under the hot sun with the Kokatat Tributary Hydration System with Reservoir. It attaches to almost all Kokatat PFDs and includes a 1. 5 liter reservoir so you can have easy access to fresh water whether you're battling whitewater or SUPing across a serene lake. The tough Cordura fabric can take a beating if you get tumbled in rapids, and a zippered stash pocket stores small accessories.
