HydraPak Stow - Collapsible Backpacking Water Bottle (350ml, 500ml, 1L) - BPA Free, Ultra Light, Spill-Proof Twist Cap

I used this item yesterday at the Swim Around Mackinaw Island challenge. It worked perfectly!! I attached it to my swim buoy with a carabiner. It didn't leak. I unscrewed the top to drink out of it b/c it was easier for me to use it that way. I liked how it collapsed when there is no liquid in it for easy storage. Before you use it, I recommend you fill it with water and a few drops of lemon juice then freeze it. Then thaw it out and rinse it. This process takes out any plastic or any bad tasting substance that might make your liquid taste bad before you use it for the first time. I highly recommend this product. I bought the 17oz.

We originally bought these HydraPak Stow collapsible water bottles for our Disney trip — we knew we’d be walking all day and didn’t want to lug around a heavy backpack full of water bottles. These were perfect!They’re super lightweight, easy to clean, and collapse down small when empty, which saved so much space in our bag. The twist cap is truly spill-proof, and the kids actually loved holding their own bottles, which made hydration way easier throughout the day.Whether you're heading to a theme park, hiking, or just want a BPA-free, ultra-light water bottle for travel or school, these are a great option. Highly recommend for families or anyone trying to keep their load light and stay hydrated on the go!

This hydrapak is amazing -- I'm a rock climber, and I've put this thing through the ringer. I attach it to my harness by putting a carabiner through the sturdy built-in loop (along with all my other sharp gear, but it doesn't pop), and it's great because it doesn't leak at all and it gets lighter/more collapsable the more you drink from it. Perfect for my adventures. I've taken it on climbing trips to Mexico and the Black Hills with this thing hanging on my harness on multipitches and chimney climbs where I'm literally squishing it with all my body weight against sharp rock totally expecting it to pop, but it survived! And it doesn't negatively impact my climbing. On my most recent trip it finally popped a teeny hole at the top; it's still usable but sounds funny because you're slurping in mostly air to get to the water, but I intend to patch it and expect it to be completely fine. But for $19, I'm so impressed that it didn't pop sooner, and the price makes my decision easy to buy a spare.Some people in other reviews complained about the water tasting funny in it -- I never noticed any issues with that. Granted, sometimes when you're adventuring you don't have access to water that tastes to one's liking anyway, and I'm not super sensitive to that as long as it doesn't taste awful. As the sun hits the hydrapak, the water starts to get warm and maybe adopt a slightly "off/stale" taste, but it didn't bother me at all. I am super impressed with this collapsable water bottle!

I've been loving this hydrapak, been using it for about a year now. No leaks so far! It had a rubbery taste at first, but I washed it out with dish soap and hot water a few times, pretty thoroughly, and the weird taste has faded with time. Folds up real well and is great for air travel, hiking and skiing. Fits in the airplane seat pocket perfectly and I love being able to throw it in my backpack and jacket pockets without any issue. I actually bought a few and they made great gifts that I could fly with in my carry on. I purchased some carabeaners separately to gift with each bottle. My friend says they like to put theirs in the freezer for ice cold water! Love the squirty dispenser too - no more pouring water on my face! Just make sure to tip the water down into the cap when squeeze drinking so you don't squirt air in your mouth, it hurts!! And I like using it for cleaning when camping and need some water pressure. Knocked off a star because I find the cap difficult to put on, you have to thread it just right and the cap is not attached so it's easy to drop when filling. My friends have also complained about the rubber taste.

These seem pretty cool. I bought 2 for an upcoming trip. We plan to put them in the cooler to have extra water available for our hydration packs at the parks. But we don't go for a couple months. I will see how we can break them in before then!They seem to be good quality. Thick enough to be reliable. The support down the center keeps a canteen shape to the bottle when filled, so it isn't too big to manage. There is a solid ring around the top you can clip a carabiner to so it can be attached to a backpack. The lid screws on, has a cap, and is a pressure valve like a sports bottle (it looks like). After the trip we should be able to use them for sporting events and other activities.

Was really excited to find this, but unfortunately it makes the water taste DISGUSTING. My kids and I could not drink from it and makes me wonder what material is leaking into the water that we're ingesting.I took it on a ski trip and used multiple different sources of water, thinking it was the water itself. I used water from the ski resort drinking fountains, bottled water, tap water, filtered water, etc. After an hour or so, the water had a rubbery, plasticky, weird taste. every. time.I don't know how it's getting such good reviews, and maybe mine my lot of water bottles was defective, but definitely cannot recommend.

Purchased a gold carabeaner and keep it attached to my caramel colored leather purse for all international travel. Works GREAT. Highly recommend. The smallest, lightest, low profile option to stay hydrated all day. Has a bit of a smell the first few weeks, so if have time get in advance and keep lid off so can air out a bit. But, even with the smell, worth it for convenience.
