Great Company Gifts

Exactly what I was needing!
[This review was collected as part of a promotion.] Ever since I lost my original Hydro Flask on a recent hiking trip, I purchased it in 2015 while working on Kauai, I've been needing to replace it ASAP. When I came across this sweet holiday deal for this 21 oz bottle, along with carrying sling, I snatched up the deal, and even bought a second one as a gift which was well received!

So happy!
[This review was collected as part of a promotion.] I received a replacement and I am so happy because my first FLASK was quite old. Even though I used it every day, the new one holds the heat much better and it’s the same Color and size.

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
