A go-to for serious cold, The Thorium's the one you reach for when you need the warmth of down to keep you comfortable outside. Created for efficient performance, comfort, and durability, it's filled with warm, lofty responsibly-sourced 750 fill-power grey goose down and has a lightweight, abrasion-resistant Arato 30 nylon shell. Down Composite Mapping strategically places Coreloft synthetic insulation in areas prone to moisture, a bio-derived liner reduces petroleum use, a DWR treatment repels water, and multiple pockets provide storage.

Note: Men's fit has been updated with a revised fit. Medium size remains unchanged. Smaller sizes are now tighter and larger sizes are now looser. Arc'teryx sizes are intended to fit the above body measurements. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.
Sleeve: With arm relaxed at your side and slightly bent, measure from center back neck, across shoulder to elbow and down to wrist.
Bust: With arms relaxed at your sides, measure under your arms, around the fullest part of your bust.
Waist: Measure around your waist at the narrowest part.
Hip: Standing with feet hip width apart, measure around your hips at the widest part.
FITTED: Patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably under outer layers.
REGULAR: Cut comfortably throughout the chest, waist, hip, and thigh. It allows freedom of movement, provides shape, and layers comfortably under our regular and relaxed fit shells.
RELAXED: Cut loosely through the chest, waist, hip, and thigh. Relaxed without sacrificing structure and clean lines, it offers comfort and freedom of movement with a more casual look.
OVERSIZED: The most generous fit is cut loosely throughout the entire body. Dropped shoulders and wide sleeves provide freedom of movement while offering drape and structure for a contemporary look.
