I have the blue one and got this one for my wife.  They hold a ton a water and have the nice handle that folds flat against the base.  The handle also has built in hooks which come in handy.  My favorite part about this is the small lock that closes over the hole that you drink from.  This ensures that water doesn't spill out when you put it in your car.

This is a great product.  Carries a lot of water yet stores very easily.  Surprised at how well it stands up when full of water, much more stable than I had expected.

Holds my 40oz Hydroflask snuggly.  I take it to the gym with me.  I don't use the shoulder strap, but the handle at the top is great.  It's rubber and strong.  Front pocket holds my iPhone 6S with plenty of room.  The smaller pocket in front can hold a few cards; I use it to hold my gym membership card.  Overall build quality is 5/5.

Nice big size, folds flat. Will be using this summer while car camping and am happy it doesn't take up much room. Filled it with water and carried it around to try it out and no issues. Stayed firm with water in it, even when set down on a table, didn't collapse which is what I was wondering about.

I use these primarily for Gin and Tonics, Mojitos, Bloody Marys, and Long Island Ice Teas. They're large enough to accomodate plenty of ice and beverage, but not so large that you feel like a lush. Sturdy and well-balanced, they clean great in the dishwasher. Because the bottoms are flat (rather than concave like a lot of glasses), water doesn't pool up in the bottom and create spots. Will probably be buying another set of these.

This actually holds more than I anticipated - like the handles and outside compartments.  Does fold flat when not in use.

So I used to bring along my 12oz columbia water bottle when I went out. I bought this 1000 oz bottle because I kind of drank a lot of water, and that's the first pro of this bottle  you don't have to constantly refill water anymore cause it can hold like 1000 oz.

Second, it has a sturdy strap. Unlike my old water bottle with a plastic strap which snapped off in a month, the strap of this bottle is indeed sturdy and nice-looking.

Third, you can actually open the lid and drink water directly through the top if you don't like drinking it through the little hold. And that also makes it easy for you to refill water as well.

If I really have to find a bad thing about this bottle, it's the fact that it doesn't have hollows on the bottle for you to put your fingers when you're holding it, while my old bottle has them. I'm still giving it 5 stars cause it's great bottle overall.

It has a lot of room, and the extra compartment at the top helps for anything that doesn't fit. We use Contigo 12oz water bottles, Thermos canteens, and still have room for apples, chips, etc. And the design is clear and is holding up well after 5x a week use for a month and a half. The handle is sturdy, as well.

This has a strong handle. Two quart capacity Gives you enough water to last more than a work shift. It is built like a rock.

its great.  Water container has handles making it easy to load water, and install it into the base each time.  Love it.

They are very sturdy and have survived the sanitary cycle of the dishwasher several times now. They sit flat which didn't seem like a big deal until I bought some very attractive ones that didn't. The silicon piece in the handle makes them easier to use with arthritic hands. So far one of the better purchases I've made. This is a real review, I was not in any way enticed to write it.

These are very nice; I purchased two for my wife and not longer after ordered three more.  They seem durable, hold plenty of water, are easy to clean (straws disconnect, freezer pack disconnects, etc.) and are comfortable to hold.

Love that they come with the D rings to attach to a carrier if needed. They collapse down very flat, but still pop out to carry plenty of food and water.

It doesn't like to fold up to store, but it is very nice for cooling down! It does a great job, as long as you are able to re-wet it frequently if needed.

It sprays a fine mist, which I wanted.  It also holds a lot of water without having to carry a large container.

I bought 2 of these, they are great ! They keep the water nice and cold and encourage us to drink more water. We take them with us everywhere we go.

The bags are nice and thick. Plasticized metal. They hold up to a bit of throwing around. The water doesn't have that bad of an off taste. I would buy and have bought them again. I am knocking one star off just because I have a hard time giving water 5 stars.
