wind – and water-resistant, very warm for its weight, highly compressible and can be worn as insulation or outerwear in cold climates. weather-resistant enough to wear as an insulated shell in a wet snowstorm, trim enough to pull on for chilly rock pitches (and still see your footholds), and warm enough for light belay parka duty on quick alpine dashes. it’s advertised as a man’s garment but the styling works as a his/hers.
