Occunomix Winter Liner Universal Blue Cotton SS551 personal protective equipment

Winter Liner For Cold Weather

The Occunomix SS551 winter liner fits under a hard hat to protect the ears, face and head in low temperatures. Its navy cotton outer shell covers a two-layer lining made from 50 percent acrylic and 50 percent polyester. A hook-and-loop adjustment secures the universal size on most wearers. A removable mouthpiece is included for added versatility.

Cotton Shell Limits Wind Protection

The cotton outer material blocks light chill but does not stop heavy wind or repel moisture. Insulation relies on the acrylic-polyester blend rather than a membrane, so warmth drops quickly in wet conditions. The liner covers the ears and lower face, yet the open crown area still allows heat to escape upward. Users needing a waterproof barrier or sealed neck closure will find this design insufficient.

Hook-and-Loop Fit With Mouthpiece Care

The hook-and-loop strap lets you tighten the liner quickly without removing gloves. Align the tabs evenly to prevent gaps that let cold air reach the ears. The removable mouthpiece snaps out for washing but can detach if snagged on collar edges. Check the fastener lint buildup regularly; clogged loops reduce holding power and cause the liner to shift during movement.
