Double the warmth without doubling the weight. Soft shells breathe, stretch, block wind, shed rain and keep you warm - all without added bulk. They are the fastest growing outerwear styles in the market today. Soft shell combines the wind and rain resistance of nylon shells with the warmth of poly fleece producing a thin, lightweight outerwear alternative. The filament that binds both layers together prevents wind from penetrating the inner layer while allowing air to circulate and moisture to escape. Eliminating the bulk, soft shell jackets provide greater mobility without sacrificing the protection from wind, rain and cold.
