The Arc'teryx Thorium Hoodie - Men's is a warm puffy jacket for everyday wear. The 750 fill power down with Coreloft synthetic insulation mapped into moisture-prone areas delivers tons of warmth, low weight, and a cozy feel when walking the winter days of the city. The roomy fit allows for bulky sweaters and layers underneath and the insulated hood is adjustable for a comfy fit that doesn't block peripheral vision.
