BRYNJE Arctic Thermo Long Johns. Brynje Arctic is a fine symbiosis of Classic and Super, that is, of merino wool and the meshed Meraklon fabric. The breathable and heat insulating Super Brynje base layer lets perspiration escape into the merino wool mid layer which then maintains the body heat allowing optimized heat insulation and highest possible moisture exchange at the same time. In short: Brynje Arctic offers the highest level of comfort in the most challenging weather conditions. Both variations can be machine-washed at 40 degrees with gentle setting and mild detergent. Superior functionality and quality of the BRYNJE ARCTIC collection ensures greatest insulating comfort, regardless of how harsh the weather may be.
