We use thermal body-mapping construction to place the insulation where it will do the most good. You already have an insulating sleeping mat below you, and most of the sleeping bag insulation that is below will be compressed by your body weight, making it inefficient. We move much of this insulation to the top of our sleeping bags where it will trap warmth from your body.Then we add an extra layer of TrueLoft™ insulation in the core body area, from the neckline to below the beltline, to help achieve and maintain the temperature ratings. This extra layer of insulation will trap more warmth from the body than comparable sleeping bags, while adding very little to the weight, size, and cost of the sleeping bag. Think of it as putting on a jacket, the first thing we all do when we need to stay warm.
We call this Critical Layer Construction.
