SubZ Lumen Jacket is an insulated performance running jacket engineered to provide warmth, weather protection, and enhanced visibility during intense workouts in cold winter conditions. Constructed with a wind-protective front panel featuring lightweight insulation, this technical running jacket delivers targeted warmth where you need it most, while brushed jersey made from recycled polyester across the sleeves and back enhances breathability, moisture management, and freedom of movement. Integrated thumbholes help keep the sleeves securely in place and provide additional coverage for your hands, while concealed zippered side pockets offer secure storage for keys and other small essentials. A taped bottom hem creates a clean, comfortable fit, and 360-degree reflective details improve visibility from every angle during early morning, evening, and nighttime runs.
