Love the look
[This review was collected as part of a promotion.] It’s stylish and the engraving is so noticeable. I was a bit disappointed I didn’t order the right mouthpiece (wanted soft) but happy with the handle which is a big improvement over the last model. My water stays cool even after being in my hot car all day! And the boot for the bottom helps it’d I drop it. Thank you for a great product!

Hydration always at hand.
[This review was collected as part of a promotion.] My kids are always drinking from my water bottle when we are out. I appreciate the 40 ounce for holding all the water we need while also fitting in my cupholder. I like the color although I thought it would be lighter. I also really like the flex straw cap it makes it easier to carry the bottle and cleaning it is also simple.

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.
