![]() ![]() From the following 15, everyone oughta be able to find something that fits their criteria for good design, great functionality, and even sometimes, affordable budget (sometimes). While some lightweight, insulated plastic options exist, too. Regardless, titanium will always be the lightest and strongest-but most expensive-option. If temperature retention is your main goal, double wall should be your go-to. But the single wall design means it won't retain heat for very long. A single wall stainless steel or titanium camping mug will be much lighter in weight and capable of being used over an open flame (meaning you can boil water directly in your mug). ![]() One last thing: the difference between single wall and double wall vacuum insulated mugs is huge-and one isn't necessarily better than the other. No gimmicks like collapsible coffee cups, tumblers, or discount specials from Amazon-just tried and true designs from well trusted brands. The following camp cups are our top picks. With this in mind, we've scoured the internet for the best camping mugs available, whether you're looking for an ultralight companion for backcountry camping trips, or a sturdy travel mug for use around town. But the right mug for backpacking may not be the right mug for car camping-or walking the dog for that matter. Use it for your breakfast oats or morning coffee, afternoon tea, evening dinner portion or nightly hot chocolate around the campfire.

But it works only under a set of specific circumstances. ![]() And copper can work to stop that last method of heat loss. “This leaves only radiation heat transfer between the walls,” Johnson said. A double-walled bottle already stops solid conduction, and a vacuum-insulated bottle stops gaseous convection. It could work, and as Wesley Johnson, a cryogenics research engineer at NASA’s Glenn Research Center in Cleveland, explained, “For spacecraft, we often use a similar technique for insulation.” The theory behind using copper in insulation (despite its being an excellent conductor normally) is based on the fact that heat transfers through three forms: solid conduction, gaseous convection, and radiation, Johnson told us. Sometimes manufacturers make bottles with copper linings in an attempt to keep the contents even hotter or colder. ![]()
