Adjustable, helmet-compatible shell with ventilation and useful pockets.

What owners are telling us.
A more substantial mountaineering shell with useful ventilation, pockets, an effective hood, and generally dependable rain and wind protection. Current-product longevity is disputed: one owner remained dry after two years of frequent use, while another reported peeling seam tape and lost waterproofing after three years. It suits buyers who value alpine features and accept stiff watertight zippers.
