Chris Livingstonwrote a review of Backcountry Hydro Flask Wide Mouth with Coffee Lid - 18oz on January 24, 2013
I found a travel mug that works nearly as well as a thermos. This mug will keep your coffee/hot chocolate/tea hot for hours even out in the elements. The 12 hour time is a little exaggerated. I would say it keeps liquids hot for 6-8 hours. I had to pick up a couple so I can use it daily.
