Hard Hat Liner by PowerPak is an economical and practical way of layering the head under a hard hat. It gives added support, protection and prevents pulling of hair. The dual-layered hard hat liner has cotton twilled outer shell and fleece lining on the inside for warmth and comfort. This flame-resistant liner features built-in pockets for warming packs. The protective liner has a silver reflective strip on the back for better visibility. The hook and loop closure makes it easy to put on and take off the hard hat liner. The elastic strip on the forehead provides a snug fit.
