Warranty Replacement

I just received my replacement Hydroflask due to a defective inner coating. This is why I love this company, as it is not the first warranty claim I’ve filed. A lifelong product that only needed to be purchased one time… sold!

Not good

Sadly, both of the bottles we just bought don’t have the cooling ability and the ice doesn’t stay cold or frozen for more than 4 hours. Disappointing.

Awesome Color

I love the bright orange. I think it is such a fun that has been created. I only wish I could have bought it in store locally.

Best bottle ever

I left my older one on the beach and was devastated without it. I ordered this new one and am in love with the product and the awesome purple color. Thank you so much!!

Cold hold

The bottle is not as insulated as I thought it would be. My hands get cold when holding and the chilled water doesn't last more than a day. Another bottle I have is better that way.
