Big Jake's reputation for hard working gloves has now been extended to our garment line. The Big Jake II series is flame resistant and made of PVC - Nomex® material, very similar to the original Big Jake Rainwear. However, the Big Jake 2 is lighter and offers a higher calorie rating than its predecessor. The BJ238BP bib-pant features durable over the shoulder elastic straps, easy release front buckles, adjustable side snaps, adjustable hook and loop ankles and fly front. The fluorescent lime background material and two inch silver reflective stripes meet ANSI 107 Class E requirements. It also meets the ASTM F1891 Standard Specification for Arc and Flame Resistant Rainwear and ASTM F2733 Standard Specification for Flame-Resistant Rainwear for Protection against Flame Hazards.
