Its integrated hard shell makes the bump cap the lightest type of professional protective head gear not requiring a protective helmet in line with EN 397, but calling for head protection in order to prevent injuries from exposure to sharp and hard edges. The VOSS-Cap pro complies with the regulations of the extended EU Directive EN 812:1997+A1:2001 safely protecting skull and temples against impact injuries. Complimented by a distinct design visually emphasizing the protective features of the VOSS-Cap pro, the improved alignment of the lock system and large vent slots provide extremely comfortable fit and make for high product acceptance.
