The opinion of Aventure Nordique
With the Radical 16H, the Polish brand Pajak offers a sleeping bag to cope with the most extreme negative temperatures. As one of the warmest sleeping bags in the world, it has a comfort temperature of -31°C and a comfort limit of -45°C, according to EN 13537 / ISO 23537.
This top-of-the-range sleeping bag is made of first-class materials. It is garnished with 1050 grams, Regular size, of 900 cuin Polish white goose down, with a 95/5 distribution. Its envelope is made of Ultra Light Ripstop Shell Gelanots, a breathable fabric that has a hydrophobic treatment. The down is compartmentalized in dozens of rooms on two levels, a 3D HH construction. Pajak took over a classic H-shaped construction and doubled it on a second level. The partitions are offset so that the seams are not aligned, thus preventing the creation of thermal bridges.
To reach such a comfortable temperature, the Radical 16H sleeping bag also benefits from IR Reflective Layer (IRL) technology. A reflective layer preserves 50% of the infrared radiation emitted by the body. Of course, it is equipped with a cold-proof flange along the zipper, a generous collar and a large hood. The double-slide zipper, elastic straps and velcro straps allow the sleeping bag to be sealed tightly to keep the heat inside. Only part of the face remains in the open air.
