The 3M™ SecureFit™ Hard Hat H-700 Series provides an excellent blend of comfort, style, and safety. 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 wearer’s head, reducing forehead pressure and increasing comfort for all-day wear.
