Radians’ Quilted Reversible 4-in-1 insulated Ripstop jacket provides superior, cross-seasonal comfort and weather protection. Radians’ RadWear® SJ510 is an ultra-lightweight and versatile jacket that reverses from dark, low-profile grey to a Class 3 Hi-Viz yellow jacket with reflective tape. The zippered sleeves can be easily removed converting the jacket into a Class 2 vest or a non-rated stylish quilted black vest, a popular wardrobe essential.
