HydraPak Stow Collapsible Water Bottle – 350ml, 500ml, 1L – Ultralight, Leak-Proof, BPA-Free, Filter Compatible Travel & Hiking Flask

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.

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.

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.

Great water bottle for nearly every outdoor activity. I mainly use this for skiing and multi-pitch climbing. It’s light, durable, collapses really small when empty, and can be clipped to a harness. I carry 2 when skiing and have 32oz of water. I also feel safer skiing with these instead of a hard water bottle, like a Nalgene, in case I fall on it. Great value.

I was going on a trip and was unsure how available water would be during my adventuring, so wanted to be able to bring a liter of water if necessary, but didn't want to always dedicate bag space to a liter bottle. This is perfect because if you put in less water, it takes up less space. And since it's flexible, it fits in a bag much easier and also decreases in size as you drink. I also found it was great for the plane because I just kept it in my lap for easy access and it didn't roll away. Honestly, awesome. I kind of want to get the smaller one, but probably don't need it since I can fill the 1L up halfway. (Also, the 17 oz bottle is the same price as the 1L on here.) Mine tasted vaguely chemically at first. I washed it with dish soap and then froze it with lemon water, and it didn't make much of a difference. There wasn't time to try again before leaving, but over the course of my trip, the weird flavor disappeared. If the flavor had been really strong, I don't know what I would have done. Note: I saw a comment about how gross the mouthpiece gets and was worried, but it wasn't an issue for me. I used it for water only, and didn't really wash it during the trip (gross, I know) because the country I was in didn't have potable tap water. That said, after 13 days, the mouthpiece still looks clean.

I REALLY wanted to love this bottle, but it’s going back. I got it for the upcoming trip to carry around in my backpack. The first thing I did is test for leakage. And it failed spectacularly. I made sure to tighten the nozzle as much as I could, but it was slowly dripping through. It also doesn’t really stay up in the fully filled state, opposite to what was advertised. But this would not be the deal breaker for me, it’s the leaking part that is not acceptable. Very sad, but I guess the entire idea of a light collapsible bottle that is also ergonomically made is still not achievable.

Love these Hydrapak Flasks. They're sturdy and leak free and a great value for the money. They're easy to clean after use and store nicely. Note: These do have a strong plastic taste unless cleaned properly before first use. a water, lemon juice, baking soda mixture works great to remove the plastic taste. Ensure you do this before first use with drinking water. Otherwise, this was a great product I purchased for my son to use while snowboarding at snowboard school at one of our local mountains. It fit great in his jacket and is smaller in heighth than the next size up. I add that because I had to search forevor to confirm before buying. It is in fact shorter than the 500ML version.

Very convenient for travel. I love these however I gave three stars because a different size I bought a few months ago is now smelling chemical and the water has a chemical taste, I have washed it well and tried a couple different filtered waters

Buen producto, se ve resistente.

Tras muchos enjuagues sigue sabiendo a plástico lo que la hace inservible

凍らせてリュックの背面に入れることで保冷剤としても活躍しました。とっても便利です。

Provato girando in montagna, eccellente.
