From the coldest days on the mountain to springtime tours that have us breaking a sweat, the C2 Primaloft Liner 3L Jacket has us covered with a versatile 3-in-1 construction. The highly waterproof and breathable shell fends off deep snow and wind, while a removable liner insulated with synthetic Primaloft Thermoplume mimics the warmth and packability of down with the added bonus of moisture-resistance.
