3M™ SecureFit™ Hard Hat H-700 Series 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. •  4-point ratchet suspension allows wearer to customize height and fit Provide proven comfort, security and adjustability
