we tested. There’s the benefit of a heating system that’s as effective as the Thermostat (the one that comes with your gas stove). But the key difference is that the warmer heats directly off the fire, which can be a safety factor.
Other factors also come into play. One is whether the warmer is safe to use in hot weather. We tested models from Weber, DeWalt, and Brother. We tried to get into this, but we couldn’t reach conclusions about whether any were unsafe to use.
We also considered the warmer’s insulation ability and the warmth that can be provided. Some warmers are designed to keep out heat, while others are designed to repel moisture. We considered both.
We did find that some warmers could be a good choice for certain people, such as people who have lower body aches. The warmth you get from a warmer will depend on your body temperature. If you’re colder than average, you may not get a high enough temperature to really heat your body.
With warmer models, there’s a possibility that you’ll not feel cool enough to be comfortable. If you aren’t comfortable warming up, you might simply choose to stop using the warmer completely.
If you’re a warmthier person, you might also want to opt for a warmer model. But it’s a matter of personal preference. When a warmer is too warm, it’s probably too warm. There are some warmers that are designed to provide the same warmth as warmer models. But there are many that are designed to provide warmth at a lower temperature.

Therm-a-Rest XTherm

We liked the Therm-a-Rest XTherm for several reasons. For one, it offers more warmth than most warmers. In our tests, the XTherm was the warmest of the warmers we looked at. The thermodynamic design and heating elements of the XTherm made it the warmest model we tried.
The XTherm also has the benefit of being able to fit in a lot of places. It comes in a carrying bag. The bag has zippered openings, which allow you to keep track of your warmer without taking up valuable floor space. I’m 5-foot-9 and 110 pounds, so I fit the bag within the stretch of a few inches of the wall.
The bag also comes with an included removable liner, which is a nice feature that’s sometimes missing in cheaper warmers. But the liner is also removable, so washing your warmer with soap and water is not an option.
There are other great features, including the Therm-a-Rest’s ability to heat up quickly, so your warmer will heat up quickly when you open the bag. And there are three heat settings, so you can heat the warmer quickly and safely.
