Workers in extreme cold temperatures and cold storage workers face one of the toughest challenges - staying productive in the cold. The Bisley Extreme Cold Collection by PIP was engineered with high-performance materials to provide advanced thermal protection against extreme cold climate hazards. Paired with a DuPont Sorona Aura multi-layered insulation, this collection of jackets, bibs and coveralls will provide workers with warmth to maintain productivity and comfort. Not compliant when they are worn alone, but when combined with Class 2 apparel, the combination satisfies Class 3 requirements.
