By combining the lightweight performance of Coreloft™ synthetic insulation, Airetica™ ripstop nylon and highly efficient ergonomic patterning, Arc’teryx created a hooded alpinist’s belay jacket that packs to the size of a water bottle and delivers effective warmth for a mere 250 grams. The fit is trim for maximum thermal efficiency, and the articulated patterning and gusseted underarms provide elevated ergonomic freedom.
Working towards the goal of minimizing weight and bulk, features are thoughtful and focused. The Nuclei’s internal pocket serves as an integrated stuff sack. A carabiner clip loop makes it easy to fasten to a harness or pack. Elastic binding around the sleeve cuffs and hood are light, smooth and create a secure fit. Hand pockets have streamlined, invisible zippers.
