Thermal Base Layer Shirt Thermowave Merino Warm Active khaki

Thermal Base Layer Shirt Thermowave Merino Warm Active Polyester Merino Dual-Layer Khaki

Thermal base layer shirt Thermowave Merino Warm Active is a next-to-skin technical garment designed for outdoor layering, hiking apparel, and cold-weather performance clothing where moisture control and insulation are essential. This thermal shirt uses dual fiber technology with recycled functional polyester on the inside and natural merino wool on the outside to ensure efficient moisture transport and reliable warmth. At only 160 GSM material thickness, it remains lightweight while maintaining breathability, antibacterial protection, and reduced skin irritation during extended use with hiking gear, outdoor jackets, and winter equipment. The combination of merino wool and polyamide fibers increases durability, elasticity, and long-term shape retention in demanding environments. MerinoDry technology enables faster moisture-wicking and extended freshness by moving excess sweat away from the body while preserving thermal comfort.
