The Skullerz 8970 Class E Cap-Style Hard Hat & LED Light is heavy-duty, yet lightweight & comfortable head protection built to protect the top of the head from falling objects or bumping into stationary objects. A padded, moisture-wicking & odor-resistant sweatband & top pad lines the sides, forehead & top interior & is removable for easy replacement. This cap-style hard hat can be worn backwards to improve upward visibility or forward to keep sun & rain away from the eyes. This safety helmet fits hat sizes 6.5 to 8 (21 in to 25 in). Customize the size with the easy-to-adjust 4-point premium ratcheting suspension. Simply turn the one-handed adjustment knob to tighten or loosen the fit without having to take the hard hat off. Built with weight distribution in mind, this hard hat's snug fit balances perfectly on the head & doesn't slip off. Style: Cap; Material(s): PC ABS; Adjusting Method: Ratchet; Thickness: 5 mm.
