The biggest feature of the actively heat-retaining material HEAT NAVI is that it absorbs almost all wavelengths of light and generates heat. Carbon-based inorganic substances are kneaded into special flat-section fibers with a large surface area, increasing the light absorption area. It becomes warm by efficiently converting light into heat. Visible light in sunlight is blocked to some extent by the outer fabric, but infrared rays, which are one of the wavelengths of light, reach the lining and filling. With HEAT NAVI, infrared rays that pass through this fabric are efficiently converted into heat, so you can feel the warmth even if you don't exercise, as long as there is light. Thank you for viewing.
