Perfect travel size

Got it through the Cairn box subscription. Love the bottle: easy to carry, practical when traveling, and collapsible.

By Annie

Great collapsible bottle!

Love this bottle! Easy to open, easy to fill, easy to add ice. Stands freely. But what is up with the lid?! It needs to be attached to the carry ring! I want to use this for hiking but if I drop it on the trail and it rolls over the edge, well - I’d be bummed! Please make the lid attached to the carry ring! I was able to attach a piece of cord under the ring on the lid and onto the carry ring on the bottle. Hopefully the new and improved model will figure out a prettier way.

Lightweight and efficient

Love this bottle. It’s very easy to open and collapse. Stands stable when filled. So much lighter than the hard plastic ones. Easy to fit in your pocket backpack. Just affix that cap!

By Winston

Good product, even better customer service.

I bought a Stash750, sadly the cap cracked a few months later. A quick email exchange with Hydrapak customer service later, I received a replacement cap in my mail. All in all, a well-designed product and great customer service!
