Bicchieri chiusi "ETALON"

Glasses with enlarged protective glass made of optically transparent shock- and heat-resistant polycarbonate. Soft PVC plastic casing with ventilation devices for effective ventilation and an elastic adjustable headband. Protection against particulate matter with a kinetic energy of at least 1.2 J. The hard protective glass layer is resistant to abrasion and scratching. The improved design of the case and good air exchange create comfort at long-term use (the lens does not mist over). Perhaps wearing with corrective glasses.
