Rockman Arborist Vented Pro Helmet System includes a Forestry ABS Helmet, 6 double pt textile harness, ratchet headband and 4 pt textile chin strap. This top of the line helmet system offers a shell construction that is lightweight with impact, heat, abrasion and chemical resistance that is better than typical PE shell construction. Its energy absorbing shape is built like a rigid cage absorbing impact by partial deformation. This lightweight thermoplastic helmet shell with UV stabilization reduces degradation from ultraviolet light. It has a short peak for better sight and an excellent ventilation system on the top of the helmet allowing hot air to expel. This helmet’s suspension system has 6 double point, textile suspension (woven nylon webbing) for excellent comfort, a patented, shock absorbing DeFromaTec ™ suspension, low nape strap, one hand ratchet headband with rear knob and long sweat band from anti allergic fleece material.
