Grundens. Sacrificial layers made of a woven nylon base fabric which has PVC applied to both sides; it is light-weight, very strong, and will not mildew. This material is remarkable for its durability, flexibility at low temperatures (-30 F), and its resistance to mineral/animal oils and grease. If torn, the fabric underneath is unaffected. From the top of the bib to below the knees there is a double sacrificial layer of material. From the top of the bib to below the waist is a triple layer of material right where it is needed most. These bibs are cut much higher up the chest. Adjustable suspenders are the new speed-clip type. The hem is reinforced with heavy nylon webbing.
