Warm synthetic Insulated Jacket – stronger by deisgn

With durability in mind, the Nuclei FL utilizes AratoTM 10r, a new ripstop face fabric designed to keep the wind out and retain warmth for rest periods in alpine conditions. Together, with CoreloftTM Continuous 65 synthetic insulation, the Nuclei FL retains loft to create a lightweight piece ideal for protecting climbers during belays, but still strong enough to hold up against harness wear and tear.

“In my entire time at Arc’teryx, I’ve never heard so much outcry for a product to return. We were able to find the perfect balance between durable and lightweight to bring back a stronger Nuclei FL, with more attention to detail and at a reduced weight.” Brylee Geddis, Product Designer

Packable and lightweight, the Nuclei FL can be easily tucked away or clipped to a harness. The adjustable, helmet compatible StormHoodTM adds warmth and protection for changing alpine conditions.

The woman’s Nuclei FL was designed by a woman, the men’s by a man, and the two designers came together to refine the features and construction for a considered and comfortable fit. Hood and cuff refinements, articulation and gender specific performance details are all built in. Long trusted by athletes and professionals, the newly updated design has been informed by the feedback of some of our most active product users.
