Review: HydraPak Stow Collapsible Water Bottle – Perfect for Backpacking & Bear Vaults! - This HydraPak Stow Collapsible Water Bottle was a lifesaver on a recent 6-day backpacking trip on the Allegheny Trail. I used it daily for my electrolyte water and couldn’t be happier with it. Why It’s Great: Packs down super small when empty, making it easy to store in a bear vault or stuff in a pack without taking up much space. Expands to a full usable size with a secure cap and easy-to-carry handle. Clipped mine on my pack strap with a carabiner during the day. Durable and flexible material that held up well on the trail. Lightweight and convenient for multi-day trips. I’m very pleased with this purchase and got it at a great price. If you do any backpacking, hiking, or travel where space and weight matter, this collapsible bottle is an excellent choice.
Review: Great foldable reusable water bottle! - Great little packable bottle! I’ve been using this for three months now regularly. Zero leaks and I have not been gentle. Hiking, cycling, traveling, and everyday walking. The carrying handle loop is sturdy and feels secure. I added a small carabiner which has been extremely helpful for clipping onto bags. The bottle did smell plasticky when it first arrived. The initial washing got rid of most of the smell and after about two more uses/washes, the smell was completely gone. This bottle is super lightweight and folds up to nearly nothing, easily tucking into its own carrying loop. Refilling is easy. The bottle is not slippery at all, even when it’s wet. It doesn’t stand up on its own, but is small enough to hold with one hand and also hold the loosed cap with your other hand. When drinking out of the bottle, you have to either suck the mouthpiece like a straw or squeeze quite hard. If you opt to squeeze, be prepared for a turbo jet stream of hydration. That is the price you pay for security so the mouthpiece doesn’t leak when the cap is flipped open. Fair trade. This bottle definitely gets condensation on the outside if you fill it with cold water on a hot day, but that’s no fault of the bottle.

### ⭐⭐⭐⭐ Works Great for My Purposes, but it failed after about 1.5 years
*by A***D on February 21, 2026*

I purchased the 500ml and use it mostly for downhill skiing. It can be stuffed into a pocket, and I can often refill it at some point during the day. For several years, I had tried using a small camelback type pack water bottle for this, but found that it wore a hole in the back of my expensive Gore-Tex jacket, so I switched to this. When I'm using a pack on adventures further from a water source, I use larger water bottles or pack compatible camelbacks, This HydraPak worked great, and I was happy with it, until.... About 1.5 years into it's use, it sprung a leak. The leak is somewhere around the bottle cap, where hard plastic meets the soft water bottle. At that point, the bottle was useless. The leak happened while the bottle was in my pack on the way to the ski hill, leaving several items wet. I've had other water bottles fail, but this seemed to be a relatively short time frame. Still, everything else about this bottle worked fine. It stashes nicely, is easy to drink from, being soft is easy to pack, and is reasonably priced. The major (and it was major) drawback is that it failed. I purchased a new one (on sale). Currently, I'll give it 4 stars for now, but a second failure in similar short order would change that and make me look for another alternative.
