Nuclei SV Parka

The Arc'teryx Nuclei SV Parka is purpose-built for the truly cold and static moments often encountered by climbers, mountaineers, or anyone needing serious warmth during long periods of inactivity in harsh environments. It's not a jacket for moving fast; it's an over-parka designed to be thrown on over your layers when the mercury drops and you're stopped dead cold, whether belaying a pitch, waiting out a storm, or huddling at camp. Arc'teryx employs a blend of premium materials to achieve this, notably their Arato™ 15 denier and 30 denier fabrics for the shell, chosen for their balance of durability, weather resistance, and minimal weight, ensuring it can handle the snags and scrapes of technical use while still shedding light precip and wind. The fill is Coreloft™ Continuous 180 and 120, a synthetic insulation known for its resilience to moisture and consistent warmth even when damp, making it a reliable choice when down isn't practical or conditions are unpredictable.
