The front of the jacket is insulated with MICROGUARD. The sleeves and back consist of NANUK knitted fleece. This hybrid design has several benefits: You get better insulation and wind protection on the front and better breathability on the sleeves and back. This combination means the jacket can be worn on its own or as an inner jacket under your weatherproof shell. Which is why it is equipped with a REGULAR system zip.
The Caribou Crossing Altis consists primarily of double layered, very warm knitted fleece. The front of the jacket is windproof so will keep you protected from that onward gale. The jacket is equipped with a system zip, so it can be used as a warm mid layer under a hardshell if required. Get double the warmth and feel comfortable on a long windy day in this Men's Windproof Fleece Jacket.
