Ready for Cold
The Arc’teryx Thorium SV Hoody is a down-insulated jacket built to keep you warm when temperatures drop. Its regular fit offers room for layering without feeling bulky, making it a solid choice for winter hikes, alpine approaches or evenings at camp.
Design Highlights
Windproof nylon shell with a PFAS-free DWR finish sheds light moisture, while a bit of stretch in the fabric and a helmet-compatible hood let you move freely whether you’re scrambling or belaying. Coreloft™ synthetic insulation backs up the goose down fill, helping maintain warmth on damp days.
Materials Explained
The outer layer blends 100% nylon with an ePE & PU membrane to block wind and resist spray. Inside, 80 g/m² of Coreloft™ pairs with goose down for a balance of loft and wet-weather reliability. Aequora AirPerm™ fabric lets excess heat and moisture escape, so you stay comfortable during high-output moments.
