HydraPak Stow Water Bottle

The Stow is made from flexible, TPU material that allows it to collapse down to the size of a hockey puck when empty. This makes it significantly more packable for ultralight backpacking or travel compared to rigid bottles that take up the same amount of space regardless of their fill level.

Yes, the TPU construction is highly abrasion-resistant and designed to withstand the rigors of the trail. While it is flexible, it is built to be puncture-resistant and can handle being dropped or stuffed into a crowded pack without leaking.

The Stow features a standard 28mm threaded cap, which is compatible with many popular backcountry water filters like the Katadyn BeFree. This allows you to filter water directly into the bottle or use the bottle as a squeeze reservoir.

No, the HydraPak Stow is constructed from BPA-free and PVC-free materials that are designed to be taste-neutral. It will not impart a plastic flavor to your water, even after being stored in the sun.

Because the bottle is flexible, you can easily reach inside with a bottle brush if needed, though it is also top-rack dishwasher safe. For a deep clean, simply rinse with warm soapy water and ensure it is completely air-dried before storing it in its collapsed state.
