Temperature and Activity Level Recommendations:
1.1 Temperature +10°C - +15°C, active movement:
Active thermal wear and long sleeves with moisture-wicking functionality (CoolTouch, Coolpass). In the warm season, combined with 2.2 (nylon jacket with insulation).
1.2 Temperature +5°C - 10°C, active movement:
Thermal underwear lvl1+ with a soft brushed interior. Wicks moisture during activity in moderately cool weather, keeping the body dry and slightly warm.
Combination: with 2.1 (fleece) and outer layer 3.1 (SoftShell) for temperatures from +5°C to -10°C.
1.3 Temperature -10°C - -25°C, moderate movement or static activity:
Polarheat thermal underwear lvl2 — elastic and warm, actively wicks moisture and retains heat.
During active movement, it wicks moisture more slowly than lvl1+ thermal underwear but retains heat better, making it ideal for cold weather and static activities.
