The Skullerz 8973 Class C Full Brim Hard Hat is heavy-duty yet lightweight and comfortable head protection built to protect the top of the head from falling objects or bumping into stationary objects. A padded, moisture-wicking and odor-resistant sweatband and top pad lines the sides, forehead and top interior and is removable for easy replacement. This full-brim style helps keeps rain away from the eyes and provides extra protection against falling or flying debris. Also offers all-around protection from the sun, humidity and heat. The open frame design with the adjustable venting offers a cooler hard hat in the heat and a dry hard hat in the rain. This safety helmet fits hat sizes 6.5 to 8 (21 in to 25 in). Customize the size and balance with the easy-to-adjust 4-point premium ratcheting suspension. Hard Hat Style: Full Brim; Material(s): PC ABS; Adjusting Method: Ratchet; Thickness: 5 mm.
