  • This is the one you've been looking for.
Size: 750ml Color: Blue
This is the second collapsible bottle purchase for me since the first from another manufacturer leaked in short order. I will use this mainly for backpacking and in my sling bag that goes with me everywhere. It doesn't leak and they provide a patch if I accidently spring a leak in the bottle. The valves are unique in that they use two different methods for stopping the flow of water. I read one review that said they couldn't get their valve to work properly. Both the straw and bottle top use the same type of double valve. Before the water will flow you need to slide the black part of the valve up. This is the first method used to stop water flow and the second is with the bite value. Super easy to use and the water flow is more than adequate. I saw another review that said it was hard to bite the valve. Maybe they didn't have the black part pulled completely out. I can't imagine it being any easier than it is. It's a very well designed valve that just takes a little know-how to make it work properly. I think if they included a little instruction card in the box on how the valve works then I think the would have received nothing but five star reviews. I couldn't detect any bad taste as one other review mentioned and the water tastes great. No smells are noticable either The bottle fits perfectly in the pouch mounted in my backpack as seen in one of my pics. The straw is easily adjusted to the height that I need and doesn't leak with the included straw sleeve. The angle of the straw can be changed easily as well. The bottle compacts down to a very small size while appearing to be very durable. The straw cleaner is long enough to fully clean the straw. I will update if anything changes but right now I'm very impressed with the really well thought-out collapsible bottle. ... show more

  • Durable, collapsible, leakproof- best water bottle!
Size: 750ml Color: Blue
Finally a soft water bottle that’s 750ml! This fits perfectly in the front pouch of my hydration backpack and is actually leakproof. So many bottles say they are and I’m always disappointed. The video instructions were super helpful, too. Love that there‘s two different ways to use it. I use the straw lid when I’m hiking, and the other lid when I’m playing tennis (it also fits way better in my tennis bag and collapses down when I’m done- way better than my bulky water bottle). I highly recommend this. ... show more

  • Will Not Race Without These!
Size: 750ml 2Pack Color: Blue
Have used these for Massanutten 100 and a UTMB 100K in Spain after extensive testing in training. They are perfect. The extra 5 oz versus all of the other brands is simply huge. You have to be mindful to screw it on flat from the start, but if I do there are zero leaks. LOVE the clear plastic cover for the spout, not only for hygiene, but I can loop that around my pinkie when it is off so that I can pour my electrolyte mix into the bottle and not lose the top. The opening IS wide enough to do that, at least with Roctane mix and Naak, though I would be fine if it were a few mm wider still) I did buy some velcro straps on Amazon to stabilize the top of them, as they do go a bit too high for both my Nathan and UD Hydration packs; and this has been a perfect solution and keeps them so stable. (Envisioned re-usable cinch straps, 1.5" X 12" work for me and prevent any bounce at all) These don't even leak when the spout is pulled up, so it's nice to not have to keep pushing it back down and to have another layer of security. Just don't pull up on it too hard, can pop out but don't worry, you can get it back in. Zero cons to this product. It's truly crazy that all the big hydration and trail running companies have nothing to compete with this gem! Will buy more soon. ... show more

  • No leak. 600ml. Wide mouth. Nuff said.
Size: 750ml 2Pack Color: Blue
First off the bottle does exactly what you want it to do, especially if you are midpack runner and not worried about having the “absolute fastest best.” Bottles have a wide mouth for easy filling, they don’t leak, and are tough. The cap for each bottle is useless unless you are throwing it in the back of your vest for longer unsupported runs. The bite valves aren’t super high flow either. But for the cost, they do exactly what you need them to do. ... show more

  • BEST decision ever
Size: 750ml Color: Blue
This was a last minute purchase as I needed the best possible amount of water in a soft flask, for the Barkley Fall Classic 50K. At 25 oz each flask I felt more confident planning for enough water in between aid stations. That was the first check mark for me. The flasks fit very comfortably, into my Ultimate Direction Race Vesta and no fuss to pull in and out. I didn't use the longer straw option although it would have been equally as efficient I am sure. The taste was "tasteless" which is always good with these kinds of flasks, and the durability was impressive. Due to the nature of this race, these flasks went through the wringer, as shown in the pic! They did not puncture or break despite my falling "on" them a couple times. I highly recommend them and I will be using them for my 100 miler in November as well. ... show more

  • Versatile, packable, and well made.
Size: 750ml Color: Blue
I purchased this product for my backpacking trips and was able to take it out last weekend. My initial thought was to just store clean water from my water filter, but quickly figured out how easy it was to scoop from streams with the wide opening. For the three day trip I used it for my dirty water bottle and it worked so well. I usually was using “smart water” bottles which always do take up some room. With this I just fill, filter, and easily pack away. I will be buying one more for clean water. I loved everything about the product and will be recommending it to anyone looking to have more packability. ... show more

  • Can't get the bite valve to work?
Size: 750ml 2Pack Color: Blue
Neither could I...at first. Unlike my other hydration flasks that you pull the clear part of the bite valve out to open, on this one, it's actually the black "base" section that gets pulled up. Works like a charm in the initial testing phase. Doesn't leak and fits my vest snuggly (Osprey Dyna 1.5)! I think it's a great design though I haven't actually tried it out on a hike yet, but all things point towards this being just what I need. ... show more

  • Easy to use and leakproof
Size: 750ml Color: Blue
This bottle works well for hydration during walking, hiking and biking. I like that it collapses to pocket size when empty and it doesn't leak. The wide opening for refilling is helpful.
