This lightweight hooded jacket utilizes MICROFT 20D high-density microgrid fabric for wind protection, water repellency, and high breathability. The interior features a float-line grid texture that reduces skin contact and prevents fabric cling during active use. Strategic ventilation holes and mesh panels are positioned based on body heat distribution patterns to optimize airflow and temperature regulation. The design includes adjustable drawcord systems at the hood and hem, invisible side pockets that maintain a clean silhouette, and soft elastic materials at hood edges and cuffs for comfort.
