Hydro Flask Double Wall Vacuum Insulated Stainless Steel Leak Proof Sports Water Bottle, Standard Mouth with BPA Free Flex Cap

これで5本目です。とても良い商品で気に入ってるからです。日本に入れると高いのが難点ですかねー

I live in AZ and use this water bottle when I play tennis outdoors in very warm temperatures. This bottle holds 24 oz of water and keeps it very cold. It is easy to clean and fits in the door of the refrigerator so it is cool and ready to grab when I head out for my tennis match.

My daughter loves her hydro flask! It’s great quality and a fab colour. Although more expensive than some other flasks it doesn’t leak and her drinks stay very cold

The reason I bought this flask for both for gym and alternative to heat water on the fire. I liked the relatively smaller size as compared to Klean Kanteen, but it cannot be heated on fire as it is not made of one single steel piece. The bottom seems to be attached separately from the body. Still keep it for gym, but went ahead and purchased Klean Kanteen for use in the wilderness.

I was replacing a klean canteen that I left at an air bnb this summer. Now that we're headed into fall, I decided to snag an insulated product. I am amazed at how long it holds cold and heat. I also prefer a loop cap. Great color choices. Of course I also dropped it during my first weekend of use (clumsy me). And as other reviewers have said the coating on the outside is rather forgiving.

I got this water bottle almost 2 years ago and I still bring it almost everywhere. It's marked up with some dents and paint chips from drops, but it still works. The only thing that I dislike about the design is that the part where one's mouth touches (the metallic ring) is exposed on the outside. I don't think that's very hygienic especially if someone else picks it up. I haven't had any issues with leaking. I normally fill it with near room temperature tap water, so I can't vouch for how well it insulates. Overall, I'm happy with my purchase.
