What a Lifesaver

The Hydro Flask kept my hot chocolate hot during a three hour ride at 10°below zero. (-10°F/-25°C). It has become a regular part of my winter outdoor activity kit.

I love the bottle. Have only used it in the summer so I can only testify that water with ice was still water with ice 24 hours later. Presumably the performance with hot liquids will be equally satisfying. I travel with it on two bicycle that have bottle cages that are more than a few years old. I had to replace the bottle cages with side loading cages to make it work. The Captcha "I am not a robot" thing is annoying

Does the job

I now have two of these. They keep my water cold, something "insulated" plastic bottles don't do.

Almost a winner

This bottle is excellent as a thermos in terms of protecting the temperatures of liquids. The two draw backs I have experienced with the bottle as a cycling water bottle is its lack of a flip top for use while moving or on quick stops. The other is the annoyance of the rattling noise that the metal casing makes in my water bottle cages. I have reduced the noise by placing bands of duck tape around the bottle, but after a week of riding, the tape wears and the volume is back up again.. I am not yet ready to return to plastic water bottles in these summer days, but I will be looking for a similar bottle better designed for cycling in the future.
