Kemier Collapsible Silicone Water Bottles-750ML,Medical Grade,BPA Free Travel Water Bottle Can Roll Up,26oz,Leak Proof Foldable Sports & Outdoor Water Bottles

This holds 25oz of liquid and the ability to fold is perfect for the suitcase. Carried my stanley on the last cruise and it was very bulky. My friend had this foldable Thermos and knew i needed on!! I cannot wait for my next vacation!!! No smell and no weird taste

The Kemier collapsible silicone water bottle is a darn good product—sturdy; easy to clean; and folds up fairly small when empty. The reasons I didn't give it five stars is because the carabiner clip isn't very sturdy (but that's easily replaced) and the silicone stretch-band that's supposed to keep it rolled up fell off and got lost on my first trip out using it. I've compensated for that by using a couple of thick rubber bands crossed diagonally around the rolled-up bottle, so that's no big deal either. All in all, it's an excellent product for the price: no weird smells or tastes; easy to clip on a bag or belt; holds a good amount of water for a longish walk; solid, no-leak cap (although you have to hold down the button to drink); and good overall portability.

I read many product reviews of various foldable silicone travel bottles. This rose above all of them, and even more so once I received and used it. The BEST FEATURE (which most others don’t have - and maybe NO others) is the air pressure release valve. This allows for a quick intake of air when the bottle naturally deflates as you suck in the liquid, and further allows for the bottle to be able to stand upright once again, rather than having to loosen the cap and retighten it for the same effect. It’s also useful when folding up the bottle to push the air out. Even the little strap that keeps the bottle folded when empty has a tiny protrusion on the end for easy rethreading if it slips out of the notch on the cap. Another plus is the attached cap cover that has a silicone patch on the inside top that connects to the mouthpiece/straw which prevents the liquid from leaking out when not in use. Further, some reviewers complained of a silicone smell but I did not have that experience . Although I knew this was not a thermal bottle, it met my needs fully, otherwise, and I highly recommend it!

got this for a 6 week trip. I actually " donated it" first, because it doesn't stand up well when empty or low. it is pretty and sounds like a good idea. so if space is a problem, maybe. I did n't try a "bag" type water bottle, but i saw several people with one. I kept and bought more of the hard plastic bottles with a flip top. So this is good quality, it just didn't work well for me.

Update: 11/20/18: This bottle made it through a pretty rugged trip to Israel and back, with a number of episodes of being dropped. It’s also made it through many kayaking day trips; the cap that protects the spout means I don’t drink river water when I put the spout to my lips. And it’s made it through day hikes, more plane trips, etc. Not a drop has leaked in any of our packs. Only criticisms are that it’s a bit wide for some bottle pockets on packs, and floppy enough that some, which aren’t very deep, can’t hold onto it. I still think this is one of the best options we could have bought. Packing a carryon for a flight is a pain. My pack always seems overly big, and then there's the issue of carrying an empty bottle through security lines. This bottle folds up and saves precious space until it's needed. It's easy to fill--it's not really as floppy as one might expect--and didn't leak at all in our travels. We spent two weeks touring in Israel, never had an issue with the bottles leaking, yet they were quick to open for a drink. The mouthpiece has a pressure valve--with the cover opened, there is a minimal risk of a spill, yet the bottle doesn't recall a big sucking action the way some of our bottles do, just pour the water into your mouth. The bottle provides a bit of insulation for those hot days, and doesn't seem to heat up the way metal or rigid plastic does.

I waited way too long to start using this bottle after purchasing it. If I could return it, I would. It is difficult to drink from.... you feel like you are getting aerated water when you are drinking successfully, which I don't enjoy. (Not fizzy water... just like you're drinking air and water.) And you stand a GREAT chance of getting half of it down your front. Also, the little valve bit at the top is an issue. While it does seal off the bottle from the rest of the air, water gets trapped above the valve and then can spill on you, your desk and/or your clothes. It's a bummer because someone clearly put a lot of thought and engineering into this bottle....but it is going in the trash. I will say, to the plus: It did not smell bad out of the box, it was easy to clean, it holds a decent amount of water, and once the drinking piece/valve part is empty of excess water (having spilled on you), it will not further spill unless you squeeze the bottle hard.
