These are perfect to keep in with your camping gear for many reasons. They do keep your coffee warmer in the summer months, because of the double wall design. This makes them more like a to-go cup. The fact that they are metal means they will hold up to the beating that your camping supplies endure, unlike a glass mug that would break. At least it would in my gear, with my family. They will also hold up better since they aren't thin aluminum that will bend easily. For those reasons these are great for camping, hiking, or any outdoor hot beverages.
These are also really nice just to keep my coffee warmer, longer sitting in my kitchen in the morning. Since I live in Maine though these are not good to use outside this time of year. This is because of the metal, and the low temperature here. When I use these outside the stainless cools down really quick, and therefore my coffee (or whatever) gets cold very quickly. This is not something that happens with just these mugs though. It is an issue I have with using all metal cups here, even with travel mugs that claim they will keep it hot for hours.
Overall these mugs are great for almost any situation. Plus if you have a stainless kitchen they would match perfectly.
