Platypus Big Zip EVO Reservoir

A taste-free hydration bag with a 5/16" drinking tube with self-sealing bite valve. The bag has a semi-rigid centre baffle for support and is easy to clean and fill with the secure slide-lock. The hose disconnects quickly high up on the bag so you don't have to dig around in your pack, and it has a leak proof shut-off valve. The reservoir is certified BPA, BPS and phthalate free and is embedded with silver ions to protect against mold and bacteria.
