The choice of synthetic insulations 3M Thinsulate and Sorona Dupont was obvious for brand recognition and thermal guarantee. A reminder of our commitment to warmth and comfort.

Light, hypoallergenic and very compressible, our insulation is above all easy to care for, as KLo products are 100% machine washable. On the technical side, our high-end insulation remains perfectly effective wet or damp, since the hydrophobic fiber with advanced water resistance absorbs less than 1% of its weight.
The science behind heat ratings is based on certified laboratory simulation results (ASTM F2732) and are provided for guidance only. The thermal comfort of your garment may vary depending on external factors (temperature, wind, humidity) as well as internal factors (fitness, hydration).
