Good Water Bottle

I keep upping the size of my Hydroflasks as the hot weather makes more and more water necessary for my daily walks. The 40 oz just about does it and I was able to use the sling from my 32 oz. , still not too heavy to carry around. I prefer Hydroflask to Yeti - the Yeti I bought just didn't keep the water cold long enough. I would not say the Hydroflask is exceptional either on that score, but I think it does a better job.

Love!

The best double wall insulated water bottles. Doesn't leak and I am comforted knowing that these are lead free!

Disappointed in ability to keep ice or water cold for long periods

Beautiful bottle but unfortunately does not keep ice cold. I can put at least 5 ice cubes in water and about 3 hours later they are almost completely melted. And it’s completely room temp the next day.

Good bottle

Keeps my ice water cold for 1 1/2- 2 days. I love that. But the outside of bottle scratches every easily. Picture is after just 2 days of use. For the price i thought it would be more durable on the outside.

Mine bottle does not work

Mine bottle does not work well. The water does not remain cool for more than two hours.

Marketed as "leak proof" when in fact it does leak

It's still a solid water bottle however since my car doesn't have a cup holder that fits the bottle sometimes it rolls on my seat and does end up leaking. I initially thought I hadn't closed it tight enough but after troubleshooting it a few times I think the design just isn't as leak proof as they say. Maybe a better water bottle for around the house
