Cold things stay cold

I like to leave this water bottle in the car because when I get back from the water will remain cold all day. The double wall construction keep cold things cold but it also makes it heavy. So you leave this one in the car so you’ll have cool water after your hike and take a lighter weight water bottle on the actual hike.

My fav water bottle

Needed the smallest size of the wide mouth I could get so it would fit in the cupholder on my TNF backpack, and this fits perfectly, even with the bottle boot on. Of course, it comes with the insulation and build quality you’d come to expect from Hydroflask. I was happy to get this specific color on sale too, I’m a big fan

Lightweight and well insulated bottle

This bottle is light so when filled with water it doesn’t feel overly heavy to carry around and drink out of. It’s also has a grippy feel so doesn’t feel like it’ll slip out of your hand. Which is also good since it does dent easily if dropped on the floor. Like that it comes in so many bright cheerful colors. The one let down is that I ordered the 24oz size but noticed that I received the 21oz size after I threw away the packaging so not able to return/exchange.

Very good quality, very good tasting water in this

Very good quality, very good tasting water in this! Much better than any other metal water bottle I've tried. Very easy to clean I can get my normal dish brush down inside. I got the 21-oz standard mouth which I like the size of because I can fit it in my purse so I don't have to carry it. Also I love the little handle on top. My husband has the wide mouth kind and I don't prefer to drink out of that. It seems to want to go all over my lap. The color is very true to the pictures. I love this water bottle! I am on my second one because the first one I dropped and I dropped it just right that it dented the bottom super badly. It kind of left a sharp edge to the crease that it made. So just beware. I did drop it about 10 times before that and it didn't do anything to it. But now I just don't drop it. They are a little expensive (yet worth the cost in my opinion) and I don't want to have to buy another one.
