The Stratos Shell from Purple Mountain Observatory is a high-performance waterproof jacket engineered for dependable protection across all four seasons. Whether you're navigating rain-soaked ridgelines in autumn, battling winter storms, or caught in an unexpected spring downpour, this shell is designed to keep you comfortable and dry when conditions turn.
At the heart of the Stratos Shell lies Toray's acclaimed Dermizax™ membrane — a non-microporous, polyurethane-based waterproof technology renowned for its superior stretch, durability, and quiet performance. Unlike traditional microporous membranes, Dermizax™ uses a molecular-level moisture transfer process that maintains consistent breathability regardless of temperature or humidity. This makes it an exceptional choice for variable British and Scandinavian conditions where weather can shift dramatically throughout the day.
The Stratos Shell is ideal for hillwalkers, hikers, and mountain enthusiasts who want a single, dependable waterproof jacket that performs confidently across all seasons. Its combination of premium Dermizax™ fabric, generous breathability, and a relaxed fit that works with layering systems makes it a versatile cornerstone for any outdoor wardrobe. If you value quality materials and considered design over fleeting trends, this jacket delivers.
