Great Bottle

[This review was collected as part of a promotion.] This summer I’ve really appreciated the ability of this bottle to keep my water cool in hot weather. The straw cap is easy to take apart and wash.

Quality Has Gone Downhill

I’ve lost count how many Hydroflasks I’ve bought and have absolutely loved. That’s no longer the case. Just bought two and they are junk. Filled them up full of ice before heading out to hike and after about a 2 hr drive, the ice was totally melted. Had a Yeti I also filled up and it was still full of ice. No more Hydroflask for us.

Good Water Bottle

[This review was collected as part of a promotion.] 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.
