CornerStone® CSJ501 ANSI 107 Class 3 Waterproof Insulated Ripstop Bomber Jacket

High-visibility protection built for cold, wet jobsites.

The CornerStone® CSJ501 is a premium insulated safety bomber designed for demanding Class 3 work environments where visibility, weather protection, and warmth all matter.

Its rugged 300-denier ripstop shell is fully seam-sealed and finished with durable water repellency to help block wind and rain. Microfleece and quilted insulation provide dependable warmth, while the removable insulated hood and adjustable cuffs help seal out harsh weather.

Durable 2-inch reflective tape provides 360-degree visibility across the body and sleeves, and the black lower body and sleeves help conceal dirt in high-wear areas. Multiple secure pockets, mic clips, and a dedicated tablet pocket make it a practical choice for crews working long shifts in difficult conditions.
