Bump cap
August 28, 2016
Weighing less than 5 ounces, the JSP HardCap AeroLite Bump Cap is the lightest full-shell bump cap on the market. AeroLite features a lightweight EPP (expanded polypropylene) impact liner combined with a tough HDPE shell – all in a baseball-style outer cap. The liner and quick-drying integrated sweatband are coated with Polygiene, an antimicrobial treatment that prevents odor-causing bacteria.
