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 BJ238PW elastic waist pant features adjustable hook and loop ankles and snap fly front. The fluorescent lime background material and dual 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.
