The Worklon 1908-M SC-3 Burlington C3 Cleanroom Raglan Sleeve Coverall is part of the SC-3 system because of its high density polyester with a carbon grid material. It was engineered to meet up to a class 10 (ISO 4) clean room demands for microelectronics, semi-conductors, disk drives, laser, and similar industries. This coverall was designed to guard against airborne particles and to dissipate static charges. The 1908-M features raglan sleeves with a zippered closure and anti-static knit cuffs. It also has a two-ply reinforced placket, adjustable snap at the collar, and three vertical snaps on the back of the leg for adjustable boot attachment.
