Reactor Extreme Mummy W/ Draw Liner

The ticking made from insulating Thermolite® material with 110g/m² increases the temperature in the sleeping bag by up to 14°C. This is thanks to the special fibers, which store maximum heat in relation to their weight and are also extremely vapor-permeable. The generous mummy cut in the shoulder area ensures full freedom of movement. In warm weather, the ticking can also be used without a sleeping bag.
