Great product and very durable. I can hang it on my pack and not have to worry about damage. Heat transfers too easily to the handle so it gets really hot when drinking coffee or tea. Solved the problem by using some para-cord and a weaving technique to insulate the handle.
The mug was shipped with no disclaimers. However, it should be noted hot liquids can cause a mug to heat up. What was surprising was the immediate and searing heat coming from the sides of the mug. I burned my hand when I picked the mug the up, instantly slinging it across the room.
Used this for coffee and spirits on a canoe trip. Only negative, very minor, was the heat from hot coffee will be somewhat intensified to your fingers when hot. Not bad on a cold day, or to have a french press river side!
I liked the nice sized cup and low weight but it stopped there. The handle has a kind of "hammered" finish that looks and feels cheep. Worst of all I couldn't get my fingers in the handle comfortably to hold the cup. If you have a larger hand or fingers, look else where...ladies, this ones for you. I love NRS and their products and I will just keep the cup and give it to someone that can use it...sorry!
