【HEAT NAVI / Heat Navi】 Light to Heat +5℃ The main 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 specially shaped flat cross-section fibers with a large surface area, increasing the light absorption area. It warms you up by efficiently converting light into heat. Warm even on cloudy days. Sunlight reaches the ground even on cloudy days. Heat Navi(R) has a lower heat exchange rate than on a sunny day, but it efficiently converts light into heat, so you can enjoy outdoor sports lightly and warmly in any weather. #Descente #DESCENTE #Training Functions: Stretch / Water Repellent / HEAT NAVI / Heat Retention We will fold it compactly and ship it.
