We recommend the kajk jumper for insulation under your drysuit, insulation during your winter activites like skiing and nordic skating.
- Order it to be snug against your skin with a minimum of air pockets. That is when it keeps you warmest.
Typical for outdoor activites is that your activity is daylong and you would stop for a bite every few hours. Those stops are the moments when the effectiveness of your clothing counts. Where the woollies under some windproof and breathable anorack. Even without an outer layer the wind is deflected by the dense material, and protects you. Humidity is transferred out and away from your skin.
