Arc'teryx Thorium Hoodie 2027 – Insulated Jacket

The Arc'teryx Thorium Hoodie is a technical insulated layer built for climbers who push into cold conditions without cutting their session short. Stuffed with 750-fill-power RDS-certified European grey goose down and wrapped in a 30-denier Toray mini-ripstop nylon shell, it delivers efficient warmth in a packable, abrasion-resistant package suited to both the crag and the commute between them.

The shell carries an FC0 DWR finish — PFAS-free — that sheds light moisture without weighing the jacket down. The updated boxier fit accommodates mid-layers comfortably, while articulated patterning and gusseted underarms keep movement unrestricted through reaches and clips. A two-way front zipper allows harness access without fully opening the jacket, a helmet-compatible insulated hood seals out wind, and an adjustable hem drawcord locks in heat when temperatures drop.

The Thorium Hoodie is the right call for climbers who spend long hours at the wall in shoulder-season or winter conditions — belaying, resting between burns, or hiking into a remote crag. The oversized internal dump pockets double as a place to stash shoes and keep them warm between attempts. If you want one jacket that handles cold-weather climbing without feeling out of place on the walk back to the car, this is it.

• Is this jacket waterproof? The Thorium Hoodie features a PFAS-free FC0 DWR treatment that repels light moisture, but it is not a waterproof shell — it is best used in dry to lightly damp conditions or layered under a hardshell in heavier precipitation.
• Can I wear this under a harness? Yes — the two-way front zipper is specifically designed to allow harness access without needing to fully unzip the jacket, making it a practical choice for active climbing days.
