Klättermusen Alv 2.0 Jacket M's | Blue Sapphire
The Alv Jacket 2.0 is a perfect mix of light and warmth. It features PrimaLoft®, which is a fast-drying and moisture-wicking insulation material. The Alv jacket 2.0 has a snug fit so you can wear it on the crag during a windy day or under a shell jacket, the perfect all round insulation option for mountaineers. The two big zipped hand pockets are placed out of the way of a climbing harness or a backpack. When temperatures are warm, it can easily be folded into its own pocket.
The Heat Conductivity Resistance System
The Heat Conductivity Resistance (HCR) system is a performance value for thermal equipment that measures the warmth of a piece on a scale of 3 to 9, with 9 providing the most warmth. HCR combines the difference in insulation materials, external conditions, and body sensitivity.
