The Stash 750 ML flexible bottle from HydraPak is the first (and so far the only) product we’ve sold out of before we even stocked it in the online shop. Our tester liked it so much that he bought three from our first shipment. Then everyone else on our staff bought the rest.

Not one of us regrets that purchase. HydraPak’s collapsible bottles are half the weight of hard bottles, and they can be packed down to fit in a pocket when empty. That makes the perfect for overnight backpacking trips, bicycle commutes, and long-distance trail runs.

From left: the Seeker 3L, Seeker 2L, UltraFlask, and Stash.

They’re great bottles. And, like every HydraPaks product we sell, they can be fitted with the E-Z Clean Membrane Filter from Katadyn. That cartridge uses a hollow-fiber filter to cleanse bacteria and parasites from water, and it screws right in to the mouth of our HydraPak bottles. When combined, the two products serve as a collapsible, lightweight water filtration system.

We sell five HydraPak products. While the Stash is meant for day use, the two, three, and four-liter Seeker products are meant to hold water for large groups or mutli-day expeditions. The 600-ML UltraFlask is a designed for runners, and comes fitted with a tube and bite valve.

Thanks to a sturdy gear loop, Seeker bags can be easily hanged from a tree or backpack.

The tube and bite valve attachment makes the UltraFlask popular among runners and ultralight hikers.

All HydraPak products are 100% BPA and PVC free.
