Love It
[This review was collected as part of a promotion.] I love my Hydro Flask! It has a cap that's are (inter)changeable. Really like the ability to purchase the straw/flip cap so I can use it easily in my car. It fits perfectly into the bottle holder on my side door. It keeps my drinks cold for HOURS!

Excellent product. Fulfillment needs work.
[This review was collected as part of a promotion.] Product is excellent. Two misses: (1) Shipping department does not know how to pack a box so that the item shipped does bang about during transit and destroy the shipping box itself. (2) Adhesive label residue on exterior of product a real pain to remove. However, with enough effort, the adhesive does come off without leaving any damage to the product. Also, get the boot, it is essential.

Best ever!
[This review was collected as part of a promotion.] Best water bottle I’ve ever seen, and I’ve tried lots of them. I’m really glad you let us engrave it. I put my last name on it. Now, when I forget to bring it home with me, someone will surely return it to me.

On the diagram (pictures) it say it can keep hot drinks up to 6 hour and in the text on the website it says up to 12 hours hot.... so which one is it?

Do they float? I'm looking for something with a closed lid to use on my kayak and with the possibility of flipping the kayak I would like to make sure I will be able to locate the flask if that were ever to happen.

I am getting a metallic taste in my water from the 21 oz flask. I’m surprised as it has 18/10 stainless steel. Is there anything that would get rid of this?

Is there a cap available for purchase that would allow me to use my standard mouth Hydro Flask 21oz with hot drinks? I purchased 2 hoping to use one for hot and the other for cold. However I have not been able to use hot drinks due to the cap. Frustrated
