Available in cap style or full brim models, the suspension system incorporates patented Pressure Diffusion Technology and sits low on the head for greater comfort and security. Select models feature a proprietary indicator that lets the wearer know when to replace helmet due to UV exposure. All H-Series non-vented hard hats meet ANSI/ISEA Z89.1 Type 1, Class G and E requirements. All H-Series vented hard hats meet ANSI/ISEA Z89.1 Type 1, Class C requirements. All H-Series non-vented hard hats meet CSA Z94.1 Type 1, Class G and E requirements. Cap-style H-700 series vented hard hats meet CSA Z94.1 Type 1, Class C requirements.The 3M SecureFit H-Series Hard Hats provides 3M innovation in comfort while maintaining the traditional cap and full brim design that many prefer. If you wear a hard hat for a full shift, you want it to be comfortable and fit properly. 3M recognizes this and has responded by designing a suspension system that self-adjusts to the wearer as the ratchet is tightened. Chosen 9 times out of 10 over current conventional hard hats*, this suspension system flexes and self-adjusts to the size of the wearers head, reducing forehead pressure and increasing comfort for all-day wear.
