These things are impressive. I thought I would test it so filled it with hot cider and stuck it in my ice water cooler for about 90 mins. When I took it out to take a sip, still burned my mouth. Just incredible!!!
And on the cold side, filled it with cold water before bed and 8 hrs later when I woke up and took a sip it was still cold. only a few degrees warmer, and I didn't even have the top on, might have stayed even colder.

Kiddos dig it

  • Familiarity: I've put it through the wringer

After everyone in my family eventually asked for a 21oz hyrdo flask for either their birthday, or for Christmas, the kids started asking as well. This was an easy present for the nieces and nephews. Instead of using their parents when they go to school/soccer/dance/etc.. they can take their own mini version. the mouth is a little large, so there will be some spills on the kids that are younger and have smaller mouths. It is entertaining though. The hyrdo flask does it's job, keeps liquid cool/hot for hours!

New perk is it is perfect to fill with hot or warm water to take with us and use to fill the babies bottle.
