Disappointed
[This review was collected as part of a promotion.] This was a warranty replacement. It doesn’t keep my liquids hot for as long as my original one used to. The contents become lukewarm within approximately 8 hours

Wrong size

A Keeper
[This review was collected as part of a promotion.] I've used a lot of brands and Hydro Flask is my favorite. I use stainless steel water bottles and this one is substantial. It fits in a cup holder. It's easy to clean.

The Perfect Size
[This review was collected as part of a promotion.] I was looking for a bottle that wasn't too big, or too small, and I found it. This bottle is the perfect size for me to take everywhere. The etching looks great that I added. Definitely worth the price.

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
