This jacket features a regular fit designed for men. To optimise its protective features, ensure the full zip is properly fastened and adjust the hood drawcords for a snug fit around your head. The Velcro cuffs should be adjusted to comfortably seal around your wrists, preventing cold air from entering. The jacket is made from 100% Polyester and is machine washable. To maintain its performance, particularly the DWR finish, follow the care label instructions carefully, typically involving a gentle cycle with a mild detergent and avoiding fabric softeners. Tumble drying on low heat or air drying is usually recommended to preserve the DWR treatment.
