Nothing beats down's warmth to weight ratio, ease of care and versatility. Cirq's Pax down jackets and vests are a great investment in warmth. They'll serve as standalone outerwear or as insulation under your waterproof shell of choice (we recommend the Rudy 3-Layer jacket for the ultimate cold weather system). Once you put on the Pax, it'll become a trusted companion for a day of deep snow, cool morning campsites or fall afternoon walks.
