When you're planning your next big summit be sure to take along the Arc'teryx Nuclei Hoodie. Featuring Arc'teryx's signature Coreloft™ Insulation that's been strategically positioned in the body, sleeves, and hood to lend warmth while providing mobility, this is the technical mid layer that will come in handy when cooler temps prevail above 10,000 feet. A clip-in point allows the Arc'teryx Nuclei Hoodie to be carried on a harness, while the jacket packs easily into a stuff sack for storage. With its lightweight construction and high warmth-to-weight ratio you'll be glad you brought along the Arc'teryx Nuclei Hoodie for wherever your adventures lead.
