Platypus Big Zip Evo 2L Lumbar

The Platypus Big Zip EVO 2L Lumbar is a 2L capacity water bladder that now delivers a 50% faster flow rate, ideal for backpackers, hikers, and mountain bikers.

The latest evolution in taste-free hydration from Platypus, the Big Zip EVO 2L Lumbar delivers a significantly higher flow rate than previous Platypus reservoirs and a host of new features, including a secure side-lock and a hand pincher grip for easy one-handed filling. It is also perfectly shaped to fit into hip sack pouches, rather than the traditional vertically shaped rucksack reservoirs.

  • Handy Pincher Grip - Allows for easy one-handed filling.
  • High Mount Quick-disconnect - Instantly stops flow and offers reliable stowing.

  • Funk-free - Embedded Silver-ion protects clean water from mould & bacteria.
  • Pure Platy Experience - All materials are certified taste-free, BPA-free, BPS-free, and phthalate-free.
