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 outer fabric's 10,000 mm water column, you are optimally protected from the elements even on uncomfortable days. The adjustable hood shields the head and neck from wind and cold, and it can be removed if needed. Velcro closures and snug-fitting cuffs leave no room for unpleasant weather and help retain body heat.
