ChemMax™ is Lakeland's comprehensive range of coveralls for Type 3 & 4 protection against hazardous chemicals. ChemMax™ 3 fabric features a UK-manufactured multi-layer barrier construction to provide protection against a wide range of hazardous chemicals. Co-extruded fabric technology means a smooth and flexible fabric that is free from the crushing and pitting suffered by adhesive or heat laminated barrier fabrics – so thickness, permeation and protection is uniform throughout the fabric surface.
