Protect Our Winters Stow™ 500ml

Took this on a backcountry ski trip and it was a game changer—the collapsible design saves so much space when it’s empty. The wide mouth makes filling and cleaning easy, even with gloves on.

I was skeptical about a collapsible bottle holding up, but the silicone is surprisingly sturdy with no weird aftertaste. It’s perfect for stuffing in my daypack after a hike, and the wide mouth makes filling with ice a breeze.

Fits in my jacket pocket even when full, and once it's empty I can roll it down to the size of a granola bar. Took it on a cold morning run and the water didn't taste plasticky at all.
