The RefrigiWear Econo-Tuff Vest is a lightweight yet robust layering solution engineered for cold-weather duty. Rated for about 15 °F (–9 °C), it combines 6 oz of polyester fiberfill insulation with a 200-denier polyester outer shell, designed to trap heat while resisting wind and moisture. Thoughtful touches like an insulated knit collar and two exterior insulated pockets keep your neck and hands protected and functional . Despite its durability, the vest remains lightweight and highly mobile—perfect for cold-storage, industrial settings, or outdoor tasks where ease of movement is key.
