The synthetic fibre and wool filling of the SylvaHe. Parka from Heber Peak provides plenty of warmth without being too bulky. In combination with the 10,000 mm water column of the outer fabric, you are optimally protected from the elements even on uncomfortable days. The adjustable hood protects your head and neck from the wind and cold. The hood can be removed if required. Velcro fasteners and close-fitting cuffs keep out the worst of the weather and keep the warmth close to the body.
