Hydro Flask bottles are great!

We have used Hydro flask bottles for almost 10 years. They are solid, leap, proof, insulated, and good looking. The dents and dings they earn on our adventures, only make them more attractive. Hydro Flask are at the top of the class.

Products are great, service is even better

I always love Hydroflask. I’ve got almost 20 bottles/cups in the house between me and my family members. We’ve been loyal for 15+ years since a friend who sold the bottles as a rep gave me one to try. I keep buying them. This bottle was a warranty replacement and Hydroflask made it super simple and quick. Yes, sometimes products aren’t perfect. From there, it’s the company that decides if the customer will be satisfied. In my case, I am. And I’ll tell others too that the investment in a bottle is protected because Hydroflask stands behind it. I’m a loyal customer.

Warranty Replacement

This was a warranty replacement. The warranty process is so cumbersome it gives the impression it’s designed to frustrate to the point one gives up.

Best Water Bottle Ever

I love my hydro flask bottles and take them everywhere. My grandson gave me a sticker with the hydro flask logo with the comment, "I knew this was the water bottles you use so I thought you would like the sticker. "

Replaced rattling bottle

Got a replacement container because my bottle started making a rattling sound. New one works well and is a nice color (old one was discontinued).
