Another Winner from Hydro FlaskThis was a long-distance Christmas gift for our 21-year old grandson. He asked for it, and since he already had one in a different color, we figure he must like them! Of course, we can attest to their quality here in Texas, too, since we drink from Hydro Flask coffee cups almost every day of the week. ;) All thumbs up.

Great giftThis was a gift for my grandson for Christmas. He asked for it and was very pleased to get it. That's why I gave it 5 stars. I didn't use it myself.

Great Bottle!Exactly what I wanted. I love the size and color of the bottle. I use it with the flex straw cap. I have bottles from other manufacturers and this is by far my favorite.

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.
Asked by: Pat G
Hello, I do apologize about the longer response time!
No, with the flask being filled they would not float. They may float if they happened to be empty at the time but I cant guarantee that.

Are any of the water bottles dishwasher safe?
Asked by: SEO1
According to the Dick's Sporting Goods packaging my 24 oz small mouth i just received is dishwasher safe? Amazon is also reporting they're dishwasher safe. But I see no marking on the bottom that says it's dishwasher safe. Please explain

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?
Asked by: David Werner
We understand how frustrating treating odors can be, but we have a quick trick to battle the issue: Mix 2-3 Tablespoons baking soda with a small amount of warm water to form a paste. The paste is a nonabrasive scrub and deodorizer. Rinse the flask with warm water. Then wash with regular dish detergent.

Can I use the lid with the straw for coffee in the standard mouth 24 oz bottle
Asked by: Reacher
Our Wide Mouth Straw Lid is compatible with all of our Wide Mouth Bottles. Unfortunately, the 24 oz bottle is a Standard Mouth and is not compatible. We have our Standard Flex Cap and Standard Sports Cap that will fit the 24 oz bottle.
