Gift from daughter. Keeps beverages cold for a long time! I recently purchased 2 Sonic slushies and wanted to save as much of 1 as I could for as long as I could. As soon as I got the slushy, I filled my Thermaflask while my husband drove. Car ride was 45 minutes in 85 degree heat; a/c in car. After checking in at hotel, Thermaflask was placed in room's fridge overnight. Took Thermaflask at checkout at noon the next day. It was left in car in similar heat until 6 pm then at room temp at home overnight. I still had some slush late the second morning! While there wasn't a massive amount of slush, I was amazed that there was any at all!! Husband faithfully fills his with ice before work and continually fills with water throughout the day. Works in vehicle repair shop so is basically out in the elements and appreciates the thermal capacity of his Thermaflask. 2 youngest kids loves theirs as well.
