Arc'teryx Men's Nuclei AR Jacket Aruna

The Arc'teryx Men's Nuclei AR Jacket combines protection and insulation for cold, wet belays and bivies. Coreloft 100 insulation is warm and resilient, and the fully seam taped Gore Thermium shell is windproof, water resistant, and highly breathable. Quilted on the inside, the insulation conforms to your body for maximum efficiency, and articulated patterning improves freedom of movement. The helmet-compatible insulated StormHood provides full-coverage protection while minimally impacting vision.
