Blaklader 4894 Underwear Thermal Top XWARM 70% Merino

Meet Blaklader's 4894 Underwear Thermal Top, a high-performance base layer designed for professionals and outdoor users who endure extreme cold. Its dual-layer system keeps you warm and dry, even in biting conditions.

• Material composition: Inner channel-knit polypropylene transports moisture away from the body to the outer merino wool layer (70% Merino), which absorbs it to help you stay dry and warm.
• Moisture management: The two-layer construction actively moves sweat outward, reducing clamminess during long wear in cold environments.
• Temperature regulation: XWARM technology helps balance your temperature so you stay comfortable as you work or move in freezing conditions.
• Temperature range: Specifically recommended for -20°C to -35°C environments, including stationary work in biting cold.
• Versatility: A reliable base layer that works under winter outerwear for extended periods outdoors or in unheated spaces.

This base layer is ideal for construction crews, utility workers, outdoor researchers, and anyone facing prolonged exposure to sub-zero conditions. The 70% Merino wool content provides natural insulation and helps manage temperature, while the polypropylene inner layer efficiently moves moisture away from the skin. By maintaining warmth and dryness, it supports prolonged comfort, reduces heat loss, and creates a solid foundation for layering in cold weather.
