The Atom SV Hoody is the warmest jacket in Arc'teryx's Atom range, made for cold days in the mountains when you are moving at a moderate pace. It was previously called the Atom Heavyweight Hoody. Warmth where you need it. Coreloft 120 synthetic insulation in the body provides warmth with little weight and bulk, while a stretchier 60 g/m² insulation under the arms and breathable side panels release heat when you work harder. It is still built for warmth first, so it suits moderate effort better than sustained high output. Weather protection.

This helps balance insulation with practical protection during everyday winter use. Internal cuff and neck gaskets reduce draughts, while the longer fitted silhouette leaves space for a layering system. A two-way front zipper makes adjustment easy, and concealed zipped hand pockets plus an internal security pocket keep everyday essentials close without disturbing the parka's clean lines. Fill power describes the down’s loft and warmth relative to its weight.

A streamlined ski suit combining a warm down-filled upper with flexible softshell trousers.

The upper uses RDS-certified 90% down and 10% feather insulation with 650 cuin fill power.

Four-way stretch in the upper and stretch softshell below help the suit move with you. The upper fabric is rated to a 15,000 mm water column, and the lower section to 10,000 mm. The softshell trousers have a PU membrane and a DWR finish that helps surface moisture bead away. These are material specifications, rather than a guarantee of complete waterproofing at every seam.

The Atom Vest provides lightweight core warmth while leaving the arms completely unrestricted for hiking, climbing, ski touring and everyday outdoor use. It can be worn as an outer layer in cool, dry conditions or beneath a shell when additional protection is required. Recycled Coreloft 60 synthetic insulation concentrates warmth around the torso without the bulk of insulated sleeves. Unlike down, Coreloft continues insulating when damp, dries quickly and resists flattening through repeated use and compression. Stretch-fleece side panels allow heat and moisture to escape during movement while improving flexibility around the torso. This hybrid construction makes the vest more breathable during high-output activity than a fully insulated garment. The lightweight 20-denier nylon ripstop outer fabric provides wind resistance and protection from light moisture. An FC0 DWR treatment helps water bead away from the surface and is made without intentionally added PFAS. The regular women’s fit provides space for layering while maintaining a clean profile. Articulated patterning supports natural movement, and the slightly lower collar improves comfort when the vest is worn beneath another layer.
