Vented safety helmet with wheel ratchet, white

Vented helmet with closable top vents for long shifts in the heat.

Designed for hot climates: six closable crown vents draw warm air out of the shell and lower head temperature by up to 4 °C. The shell is high-durability HDPE to EN 397 with a six-point textile suspension and a replaceable sweatband. The wheel ratchet adjusts one-handed, gloves on. Not for electrical work — the vents void the electrical insulation claim.
