This active insulation hoodie is made with highly breathable and stretchable Stretch Nylon and Stretch Octa Bonding. Octa provides excellent dynamic warmth and is positioned on the front, shoulders, upper arms, and back, along the erector spinae muscles, the largest muscles in the body. Compared to the Sub Jacket, which has Octa placed all over the jacket, the Octa is placed less over a smaller area, providing better breathability and preventing overheating while maintaining moderate warmth. The hood, side panels, portions of the arms, and back are made of softshell, providing a comfortable fit and stretch. The hood fits snugly around the head, and the center zipper with a double zipper can be opened from underneath for efficient ventilation. This jacket is ideal for year-round activities that prioritize dynamic warmth, from trekking to mountain running and backcountry adventures in the depths of winter.
