The filling made of synthetic fibers and wool in the SylvaHe Parka by Heber Peak provides plenty of warmth without being too bulky. Combined 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 the head and neck area from wind and cold, and it can be removed if needed. Velcro fasteners and snug-fitting sleeve cuffs leave no openings for unpleasant weather and help retain body heat.
