The 3M SecureFit H-Series Hard Hats with Pressure Diffusion Technology are designed to self-adjust to the wearer as the ratchet is tightened. This helps create a personalized fit and reduces the pressure on the forehead up to 30% compared to current 3M H-series hard hat suspensions. The smooth, easy turning ratchet suspension sits lows on the head to increase security and reduce pressure, helping to make the SecureFit H-Series a comfortable and stable hard hat option. Choose from cap or full brim style in a gloss finish.
