Activital TERAXCOOL Thermal Cooling Arm Covers, Gray

Terahertz ore has the power of "thermal radiation," converting absorbed heat into far-infrared rays and radiating them into the atmosphere. Furthermore, when the radiated far-infrared rays collide with sunlight's far-infrared rays and cancel each other out, they partially block (heat-block) the sunlight's heat energy from entering the body. Terahertz ore is used as the main ingredient, and rare metals and rare earth elements necessary to enhance its functionality are blended into a tiny powder. Printed on the fabric surface is a grid pattern with efficient far-infrared radiation, creating an inner layer with heat-dissipating and heat-blocking properties. The original knit fabric, made of 85% nylon and 15% polyurethane, has a smooth, cool-touch feel (Q-MAX value 0.333), a comfortable feel, excellent breathability, UV protection of 97.9% (gray-white), UPF 50+, and quick-drying properties.
