The HardCap AeroLite® provides complete protection in its category, meeting the requirements of the EN812:2012 BSI Standard. At only 135g, the HardCap AeroLite® is the best performing lightweight bump cap on the market. It has a lightweight EPP (Expanded Polypropylene) impact liner combined with a tough HDPE shell and a lightweight baseball cap style outer cover. The integrated, moisture wicking sweatband and comfort liner have a Polygiene® anti-bacterial treatment. Large reflective panels on the side of the HardCap AeroLite® add visibility. Increased resistance to staining of the outer lining comes from a DWR (Durable Water Repellent) coating that causes water to bead and roll off of the cap.
