Hydrapak Stash 1L

rated 3.0 of 5 stars
photo: Hydrapak Stash 1L water bottle

Nice light alternative to traditional Nalgene bottles.


  • Smaller profile and lighter than Nalgene
  • Collapsible when empty


  • Smaller top opening
  • Not rigid so requires care in use
  • Cost

I have used traditional hard plastic Nalgene water bottles for years and years (decades, actually). Recently I got a Hydrapak Stash as an alternative. I like its lighter, smaller profile, and its ability to collapse, thus using less pack space when empty.

It is pretty durable, but it "could" be punctured (unlike a Nalgene). Its non-rigid design takes some adjusting to when holding/balancing it for filling and drinking. The opening is smaller than a liter Nalgene bottle, which means more care's needed for filling and cleaning.

Although I can quickly treat a liter of water in a Nalgene bottle using my UV Steripen, the smaller mouth of the Stash makes Steripen use difficult.


I am putting the bottle through its first season of use.
