This is one of my favorite camping items. Extremely well made, and lightweight for a double walled mug. It does keep liquids warm/cold for much longer than my single walled cups. The handles are a little "floppy" but overall they are fine. Definitely get the lid that goes with this cup. It increases the temperature retention of the mug significantly. I store my creamer and sugar in the cup, with tea in my portable tea steeper.
Definitely appreciated on winter camps. I have also begun keeping it in my office and using it there when not camping. When not using the lid, I have noticed that the rim of the cup has a nice curve to it, and is easy to sip from, unlike so many other mugs that have sharper angles or a rolled edge.
