3M SecureFit H-704SFV-UV Safety Helmet (Vented, Class C, Uvicator)

The 3M SecureFit H-704SFV-UV is a genuine 3M vented hard hat designed for hot, humid conditions. It combines shell ventilation, a 4-point ratchet suspension and a Uvicator sun-exposure sensor, so workers stay cooler and protected through long outdoor shifts.

Product overview

The H-704SFV-UV is a vented member of the 3M SecureFit H-700 Series. Because the shell has ventilation openings, it improves airflow and comfort in warm climates, which suits Vietnam’s tropical conditions. It is a Class C (non-electrical) helmet for impact protection, and the Uvicator sensor fades over time to show when UV ageing means the helmet should be replaced.
