The hoodie is constructed using four types of fibers that sit inside the garment like springs and will provide enhanced loft and stretch to maximize comfort. These fibers will move with the wearer to keep them feeling flexible as they go, but will also loft out when not in motion to enhance warmth and coziness.
The Ventus Active Hoodie is positioned as warmer than a conventional base layer but isn’t intended to function as a replacement for lightweight down jackets. The hoodie is finished with a DWR coating for enhanced water resistance.
