Engineered to withstand the harshest winter conditions, this thermal innerwear combines zoned heat-boosting technology with moisture-resistant Jech-Clo3.0 insulation, ensuring comfort and warmth even in extreme cold from -15°C to -5°C. With innovative dual-layer insulation and precision-fitted cuffs, this lightweight yet warm design effectively blocks cold winds, keeping you warm and mobile during winter outdoor activities.

Key Features

• Zoned Heat-Boost Design:
  Increased insulation in high-risk cold areas such as the chest, back, knees, and shoulders ensures enhanced warmth and protection against cold spots.

• High-Performance Insulation:
  Jech-Clo3.0 Insulation offers a thermal rating of 1.36 Clo, comparable to 800 fill power down, delivering outstanding heat retention even in damp environments.
  Full Body Dual-Layer Insulation: The dual-layer design increases warmth by over 30%, with infrared heating technology raising the temperature by an additional 2.2°C, ensuring consistent warmth even during prolonged periods of inactivity.

• Windproof Warmth:
  Precision-Fitted Cuffs and Hems: Double-layered edges at the neck, sleeves, and ankles effectively seal in warmth while preventing cold air from entering. The reinforced hem areas provide both comfort and extra insulation.

• Lightweight Comfort:
  Equivalent to wearing one thermal layer plus an insulated vest, this piece delivers maximum warmth with minimal weight, making it ideal for outdoor activities without feeling bulky.
