Great water bottle with handy strap
Great water bottle. Keeps drinks cold for hours, even when I'm outside in hot weather. I like the handy strap so it's easier to carry. The only downside is that it does not fit in a car cup holder. It's more of a bottle you'd take when you're going to be outside for a longer period.

Quality Bottle
So I've had this bottle for a week or so and I'm relly enjoying it. I live in a hot sub tropical climate and wanted a drink bottle that stays cold and this one really does. I bought a big ice cub mould and those big cubes have lasted for around 5 hours in the bottle. Even after they have melted the water is fridge temperature cold for around 20 hours and then it's still very refreshing until around 24 hours. I'm really impressed. I also love the colour and the surface finish of the bottle is really nice and very anti slip. I find the straw really convenient and I love that it closes tight so no bugs can go in there. One thing I would say is with the straw lid, its not water tight. I haven't tested the other lid. I just carry the bottle around my house so it doesn't bother me. I do like the strap that comes with the bottle but it's a bit tricky to attach and I worry that the plastic ring might eventually break further down the line, but not anytime in the near future I don't think. All in all I would 100% purchase this bottle again and may get another for my husband.

Best dang water botthe ever!
Unlike other bottles I have owned, this bottle has kept my drink icy cold and undiluted by premature ice meltage (Look! I made a new word!). Seriously though, nothing irritates me more than waking up to a lukewarm, watered down beverage. This is no longer a problem. I love this bottle!

Nice bottle
Great bottle. Doesn’t keep the liquids cold very long. Easy to clean and is leakproof. Just what I needed to get my water in. Perfect size. The color is perfect. I like that it came with two lids one with a straw and one without. Worth the money in my opinion.

Water gets stuck between the walls
Worked well for about a week. After that I couldn't drink out of the straw attachment. I was fine with that. Have spent the last year using it with the other drinking attachment. Recently took it in a camping trip and when we came back there is now water stuck in the double walled lining that we cannot get out. I'm now to scared to use it due to mold and corrosion and will be throwing this away :/ what a waste of $30.

Great product but...
This is a great bottle, and it does keep our water cold for a long time. The con I have with it and why I did not give it five stars is the outer material. It is rougher than expected, and although it does keep the bottle from sweating, it gets dirty easily and is hard to clean. I think the material rubs off as well.

Very happy. Good size for sports.
It’s great. My daughter wanted a large bottle to last her basketball training, which it does. And it’s very pretty so a win win.
