Sportszu Flexible Collapsible Foldable Hiking Reusable Water Bottles, 700ml, Set of 3

These are great! I am hesitant to leave 5 star reviews, but I can't couldn't come up with a negative for these, so 5 stars it is! They are very lightweight, hold a decent amount of water, are easy to drink from, the cap stays on while drinking (I read many reviews of other similar that complained of caps unscrewing and getting lost), wash and dry easily, and fold up! That is the icing on the cake here, I had forgotten they could be folded up and held folded by the cap, and that's a great feature.I bought these for my children to carry in their travel backpacks, and they've been great for that so far. Admittedly, they are a little difficult for the kids to hold and drink from when they're full because they can't squeeze it tight, but once it's not as full, my 3 and 6 year old can use them solo.It's only been a few months, but right now, is definitely recommend these!

I bought these for an upcoming trip and am just testing them out to make sure they work before I pack them up for vacation. My problem is that, although everyone says they stand up, my set does not have a flat bottom. I read another review that said the bottom did not expand on the first fill, so they used a straw to open it. I tried - no luck. My bottles are sealed around all 3 edges completely. Since the pouches are clearish, I can see the extra material inside that is supposed to expand for the flat bottom but it has no where to go since the bottom edge is sealed all the way around.No real leak problems yet - one has leaked a little after I filled it but that's only because I was messing with it to try to get the bottom to expand and in doing so, I turned it upside down. But as long as I keep them upright, I don't expect any problems.We'll see how they perform on my trip but for now I'm just wishing they would stand upright as advertised.

It is the right volume for me (0.7L). However, since the base is not rounded it is hard to get into my backpack's water bottle holder since the edges tend to snag in the mesh of the pack. I am thinking of trimming it to round it up a bit, but I think it will create a leak. The other option is of course to hang it somewhere either in your belt loop or backpack, but I don't like to have things swinging around, it just make the long hike seem more tiring.

Water tasted a bit funny, and has a pretty flimsy clip. It served its purpose-water for the amazing Women's March on Washington, Los Angeles (the best part of this purchase was what I used it for), and will come in handy for times I don't want to carry a big purse or backpack but need water.

We took these to Disney World recently and they worked out great! We filled them up with water from the water fountain or you can ask for free cups of water at most quick stop eating places. They didn't leak, were easy for the kids to operate, and clipped nicely to the stroller so we didn't have to carry them! They rolled up nicely when we put them away. The only con is that they are not insulated so the water warmed up quickly if it stayed in direct sun during warmer weather.

These work well, but there are some things I don't like about them. For one it's pretty impossible to get them to dry out completely since the plastic wants to collapse in on itself, so mildew is a concern. It's also kind of awkward to hold. There's a lot of extra plastic along the edges which makes it pretty large. Also the logo is ugly. All in all though, it served me well for the price. I bought it to take with my to Japan and it served its purpose beautifully. I am happy I bought this because there are next to no water fountains in Japan, and the drinks you get in restaurants are tiny- usually no refills either unless you're eating curry. Good buy!

Bought these before a big trip overseas and they are perfect! Appreciate that they come as a 3 pack. We've used them on numerous trips since and they've held up really well. Love the hook they come with so you can strap it onto your backpack or a belt loop. The greatest thing feature is that you can condense them down when not in use so you can save on valuable limited travel packing space. Would highly recommend!

These water bottles can be used for so many activities! Saving $4/water bottle at the airport past security, hiking, theme parks, and most importantly - entertaining a bored baby. I had a collapsible bottle before that wasn't quite so crinkly so I'm not sure how long these will last since I use these frequently. But, it's worth the price and convenience I'd buy them again.
