OccuNomix Baseball Bump Caps are a one size fits all, high profile, 6 panel designed hard hat with cap holes for cooling air flow. There is a solid PE cap insert that encircles the top, front, and both sides of the head to protect against bumps and scrapes while securing easily into these hats that are ideal for industries like food and beverage processing, meat packing, warehousing, auto repair, home inspection, mechanical work, meter reading or pest control; industries where blows to back of head are not an issue. These caps are not ANSI compliant.
