Sierra Designs Prima Fusion
The Prima Fusion is an insulated hardshell with a few key differences. First, it's insulated only in strategic areas along the chest, back, shoulders, and tops of the arms. The uninsulated sides, helmet-compatible hood, elbows, and pit-zip-equipped underarms make it significantly more breathable. Second, the outer fabric is cut from a heavier-weight nylon making it considerably more abrasion-resistant.
