ULTRALIGHT protector jacketwith STF (SAS TEC Foam) protections, totally made from airnet material. 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. Features Made with polyester mesh and Airnet material Internal protection in STF (Sas Tec Foam) removable for washing Maximum lightness Maximum transpiration Increased elasticity to absorb shock Back protector: EN1621-2 LEVEL 2 Chest protector: EN1621-3 LEVEL 2 Shoulder protectors: EN1621-1 Elbow protectors: EN1621-1
