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. Footnote: **End-user survey conducted by 3M, November 2020 � March 2021. Participants were allowed to keep the new 3M hard hat.
