This lightweight shoulder-length thermal liner is extra-long to keep head, ears and neck covered while fitting comfortably under helmets or hard hats without bulk. The unique zip-off cap design allows workers to remove the bottom part of the liner for wear alone as a thermal FR skull cap. It can also be buttoned atop hard hats to keep the bottom up and out of the way.
To attach to a hard hat, remove the suspension and thread the system through the four slots in the liner. Then, secure the four hook & loop points to the suspension before inserting back into the hard hat.
