Why We Like The Nuclei FL Jacket

The Nuclei FL Jacket is a magnificent midlayer for moving fast in the alpine whether we're climbing, touring, or trekking. It adds that special touch of insulated warmth that we look for when we're on the go in colder climates. We also like that it's windproof when brisk breezes greet us on ridgelines. The shell's water resistance is reliable in passing showers or the occasional snowfall, and Arc'teryx fitted it slim so we can layer a shell over it in more extreme conditions. Despite a slim fit, the Nuclei FL is super easy to move around in when we're belaying and transitioning from uphill to down.
