The K-Way Claude 4.0 jacket reinvents the classic with a 100% recycled nylon ripstop construction. Its 10K waterproofness and equivalent breathability offer optimal weather protection without compromising comfort. Heat-sealed seams and an internal wind flap provide a reliable barrier against wind and rain. An adjustable hood and hem, zippered pockets, and back ventilation cutouts complete this functional design.
