Perfect system and easy to clean. No special equipment.

  • No sloshing
  • Great water flow

  • No dust cap on bite valve

I got this for my daypack that has a spot for a hydration reservoir. This hydration delivers on all levels. Good water flow, easy fill, easy clean.

I used this during an OCR event and sometimes filling your pack can be a pain to fill when running. This was no issue. Top slides open and fills quick. Even running with this didn't slosh around.

I'm very happy with the configuration.


What is "shape shift technology?" I'd love to hear more.

The "shape shift" is a plastic, flex, joint that works kind of like a ziplock. It joins the two sides and pinches in the middle. Easily separates for cleaning.

Thanks for the review, Tom. What size is yours?

Sounds similar to the new Platypus reservoir I'm using.

I'm using the 2L size. There is a 3L size as well.
