Arcteryx Thorium Women's Vest

For core warmth without the bulk of sleeves, the Arc'teryx Thorium Women's Vest brings responsibly sourced down to a packable, durable hooded vest. It warms your core while keeping your arms free to move, then stuffs down small when you do not need it. It is the versatile layer that bridges cool mornings and cold belays without overheating.

Why we like it:

A hooded down vest is an underrated layering tool, and this one nails it with a low-profile insulated hood that adds warmth without getting in the way. It is the piece that lives in your pack for just-in-case chills.

Features and Functions:

The Thorium Vest is filled with 750 fill grey goose down certified to the Responsible Down Standard, under a durable, packable Arato 30 nylon shell with an FC0 DWR finish and a light, down-proof 20 denier liner. Down Composite Mapping adds Coreloft synthetic insulation in moisture-prone areas, a low-profile insulated StormHood adds coverage, and a stuff sack makes it easy to carry.

Fit and Sizing:

A regular fit sits over a baselayer or fleece and tucks cleanly under a shell. True to size, trim enough to avoid bulk under outer layers.

Bottom Line:

For core warmth on the move, the Thorium Vest is best at aerobic cold-weather days and as a packable layering piece. A smart choice when a full jacket is too much but a baselayer is not enough.
