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.

  • Optimized Comfort: With 2 levels of height adjustment. Contains a premium washable and replaceable sweatband that is made of moisture-wicking material designed to help keep workers cool and dry
  • 3M Uvicator Sensor: A visual cue when it’s time to replace the hard hat due to UV exposure
