Arc'teryx Nuclei FL Jacket

Light, wind resistant, and packable synthetically insulated hoody for climbing and other alpine pursuits.

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 wind resistant and durable, Coreloft™ Continuous 65 insulation provides effective warmth – even if wet – and the insulated StormHood™ adds protection.

The Arc'teryx Big Mountain Weekend is back again in the beautiful Langdale Valley on the 8th - 10th May. Join us for clinics, aimed to educate and improve your mountain and crag skills and come and enjoy live music, BBQ and beer at the Sticklebarn event base camp. The Langdale Challenge will be available to take part in all weekend and our event partners will also be on hand to offer out the very best advice, demo gear and samples.

As always we have refined our clinics again this year to make sure we are providing you with top-notch information from the very best British Mountain Guides at the ISM. We are proud to present four new clinics including Overnight Wild Camping, Fine Tune Your Trad Climbing and two Environmental Clinics: Sphagnum moss planting and tree planting.
