Craftright Safety Helmet

An ABS plastic Type 1 hard hat certified to AS/NZS 1801:1997, so it is site legal for construction, industrial and mining work. It has 25 mm moulded slots on both sides, which is what you need if you later want to clip on a visor or a set of earmuffs. Cheap enough to keep a spare in the ute for whoever turns up without one.
