Tough and hot

Seems solidly built as advertised. Drinks definitely stay hot better than any of my other flasks, I haven't tested it for the full 27hrs hot advertised yet, but perfect for making in the morning and drinking in the evening.

Stanley Master Vacuum Bottle

10 out of 10. this is the best flask I have ever had. Holds hot water for what it says. I tested it for 24 hrs hot water indoors and 12 hrs outdoors in Nov.
