Big Zip EVO 2.0L Lumbar Water Bladder

The ultimate water reservoir for running and biking adventure

Platypus’ latest invention is perfect for the thirsty trail runner or bikers – this nifty water reservoir is designed to sit across your lumbar, perfect for use in a lumbar pack. The Big Zip EVO delivers a significantly higher flow rate than previous Platypus models, meaning you won’t be struggling to gulp down some refreshing water after a lung-busting ascent. As with all Platypus reservoirs, you’re guaranteed taste-free water, so no more sipping disgusting plastic tasting swill. We particularly love its leak-proof shut off valve, which means you won’t have any water dripping down you after you’ve had a drink. The Big Zip EVO is super easy to fill, with a secure slide lock that ensures no leaks. The semi-rigid centre baffle means you don’t end up with a super bulky pouch sitting uncomfortably across your back. And the baffle makes it easy for cleaning and drying too, although thanks to embedded silver-ion the reservoir is protected from mould and bacteria.
