Built with advanced specifications, this shell jacket delivers exceptional defence against rain and wind whilst maintaining superior breathability for sustained outdoor activity. Weather resistance is engineered throughout. The PFC-free DWR showerproof finish rated to 600mm water column and 1000g breathability ensures reliable protection against precipitation and wind whilst allowing optimal moisture vapour transmission during intense exertion. The mesh lining enhances ventilation and comfort, preventing moisture accumulation and creating a lightweight feel ideal for layering or independent wear across seasons. Refined engineering elevates both functionality and user experience. The concealed adjustable hood adapts seamlessly to varying weather conditions whilst preserving a streamlined aesthetic, whilst the full-length zip features a protective chin guard and inner zip guard to prevent snagging and effectively seal out cold air. Reflective detail on shoulder seams enhances visibility during low-light conditions, critical for commuting and outdoor pursuits. A mesh-lined back vent optimises airflow during demanding activity, preventing overheating. Two front zip pockets offer practical storage for essentials, whilst tear-release adjustable cuffs provide customised fit without restricting wrist movement. A drawcord hem enables precise adjustment for optimal coverage and thermal efficiency. Branded zip pulls and right hem add professional finishing touches, whilst the innovative pack-and-zip-into-front-pocket design transforms this jacket into a compact travel essential.
