ERGODYNE N-Ferno Winter Hard Hat Liner, Flame Resistant, Thermal Fleece Lining

The ERGODYNE N-Ferno winter hard hat liner family features a 2-layer design with a flame-resistant outer shell and a comfortable polyester fleece inner lining for reliable warmth and fit under helmets. Outer shell construction is listed as a modacrylic/cotton blend (60% modacrylic cotton and 40% cotton twill blend in product details) with a 100% polyester fleece lining, offering inherent flame-resistant and self-extinguishing properties while remaining lightweight. Liners include an elastic forehead gather to trap heat, a hook-and-loop chin strap, and four exterior hook-and-loop straps to attach to hard hat suspensions; small pockets near the ears accommodate hand warmers and some SKUs provide attachment points for optional facemasks. Available in one size and shown in black, these liners are designed to provide ear-to-ear warmth under hard hats without adding excessive bulk. Please note this garment is not entirely fire-resistant.
