Valkyrie EVO chest protector with back protectors is available in two versions (long and short) and in two colors. Valkyrie EVO is made with innovative SAS TEC / KOROYD technology. With their SK-protection-series UFO combines the positive features of SAS-TEC. foam and Koroyd Cores to something completely new: lightweight, breathable and highest damping capacity. SAS-TEC - Safety made of foam Unlike conventional PU foam, SAS-TEC s polyurethane viscoelastic foam is partly made of renewable materials. Its special features include spontaneous response, maximum comfort and unique damping performance, with excellent near-linear energy absorption. The special microstructure of SAS-TEC foam is responsible for adaptive impact energy damping behavior: the higher the impact speed, the greater the foam s resistance. All these features provide the best possible protection for the body. Koroyd Cores - Performance and breathability The combination of the precise extrusion process and Koroyd s unique thermal welding creates an extremely high and consistent performance structure with superior impact energy absorption and breathability. On high speed impacts the cores crush in a fully controlled manner, decelerating impact energy and significantly reducing final trauma levels. Koroyd s fully open cellular construction channels ensure airflow and breathability without limitation. Features Extremely light and anatomically designed It is particularly suitable for cross and enduro Back protector: EN1621-2 LEVEL 2 Chest protector: EN1621-3 LEVEL 2
