Fabric: A knitted polyester base material (2.6 oz. per yard), laminated to a PVC polyurethane layer (2.4 oz. per yard), for a total weight of 5 oz. per yard. The strength to weight ratio of this fabric is remarkable–an entire set (jacket and bibs) weighs just 2 pounds. Surprisingly tough, this fabric is suitable for many activities. Another attribute of this material is that it is quiet, an important consideration for hunters. Applications: All Commercial Fishing, Building and Road Construction, Timber Harvest, Agriculture, Mining, Shipyards, Forestry, Utilities, Hunting, Food Processing, General Boating. Features: The Petrus bibs feature a trimmer cut and fit than our Herkules pants. Reversible front/back. These bibs do not have a waist gusset but instead are cut much higher up the chest. Adjustable suspenders are the new speed-clip type.
