Question: What volume of liquid do they hold?  Thx
Document: I can't believe I paid in bucks rather than Chinese Yuan for it. You must push the flexible lid hard to keep the liquid inside the bag. The platic lid at top has no function.
Unless you suck the water out just right or forego using your mouth at all and just pour by up-ending the bag, liquid leaks out underneath the cap, from within. It seems like a standard bottle top thread, so I may just replace them when I find a suitable replacement commercial cap laying around.Later Edit: I brought 3 of these for a Europe trip. I left 2 on a bus, and now the third has stopped holding water, after about a month.
this is a neat thing to have. I like that i can easily fit it in my purse or bag. now i just have to remember to use it! i would recommend getting more than one. and replacing water bottles with these. The price plus shipping is still cheaper than the ones I have found at stores.
in the announcement had 5 bags and only sent me two, and the colors were very ugly, I did not like anything, I will not buy mor.
We love these. You can put them in your pocket or hang them from a belt loop. As you drink you can roll them up to take up less space. We bring them skiing, snow shoeing & hiking.
These are great water bottles, however I thought from the picture that I was ordering 5 for the price, not 1 (one). I was pretty sad when I opened the package to only find 3 water bottles instead of the 15 I thought I had ordered. Was going to use these as gifts.
The bags work well for what they are. Unless you have a very short faucet or short drinking fountain stream, they're not hard to fill up, if you inflate them first. They compress down nicely to just the top and a small roll, the carabiner works well and doesn't rip the bag or anything, but is not high quality, so it breaks easily--be prepared to push the spring tab back in somewhat regularly if you use it.My complaint mirrors others': The top.
Of an order of 8, I received 4 of 2 colors. Was hoping for more of a variety. Of those, 3 of the bags wouldn't open to stand, they were sealed closed, and 2 of the lids leaked when laid on their side.
Liked that these bottles are easy to clean and easy to fill. Great for kids to use, my boys just roll them up and put them in their backpacks without the worry of it being smashed.
I love this water bottle. I bought it to take with me for hikes. It is so convenient. Very durable, It collapses & folds Easy to take along . This is great for anybody it can go anywhere.
