Fast and light alpine travel’s static phases require you stay warm while protecting yourself from chilling winds. Inspired by persistent athlete demand, and redesigned to their exacting specifications, the next-generation Nuclei FL Jacket is lighter, more resilient, and delivers outstanding thermal performance for remarkably little weight. The Arato™ 10D ripstop is windproof and durable, Coreloft™ insulation provides effective warmth – even if wet – and the insulated StormHood™ adds protection.
