Our Alpine Series Icefall Jacket is a proven choice for weight-conscious climbers. It combines technical fabrics and fill to provide exceptional warmth in damp, snowy conditions. Its ultralight Pertex Quantum shell is a 100% recycled nylon with Y Fuse technology. This fabric increases fabric performance around snow, and a DWR coating ensures water can bead and roll off its surface. Water resistant HyperDRY goose down is through the body, arms, and hood, and synthetic PrimaLoft Gold insulation is in the chin, shoulder and cuff panels. PrimaLoft Gold uses Cross-Core Technology to form a barrier against the cold — effectively providing warmth at less weight — and the combination ensures effectiveness in moisture-prone areas. Our Alpine Series is the direct result of our partnership with the New Zealand Alpine Team (NZAT). This team of elite mountaineers demand premium lightweight equipment that doesn't compromise performance. The main and inner fabrics are bluesign certified, which means they were manufactured with the responsible use of resources. The Responsible Down Standard (RDS) is an independent, voluntary global standard in the ethical sourcing of down and feathers, and HyperDRY down is treated with a PFC-free compound to provide water resistance in technical environments. All Macpac down is RDS certified. A technical down jacket for weight-conscious climbers. Made from a combination of highly compressible down, synthetic insulation and specialist fabrics for exceptional warmth and packability.
