Atom Vest Women's

When mountain trails turn chilly or ski touring conditions get unpredictable, the Arc'teryx Atom Vest Women's delivers reliable core warmth without restricting your movement. Unlike down vests that fail when damp, the Coreloft™ 60 synthetic insulation maintains its thermal properties even in wet conditions, while performance stretch fleece side panels provide crucial ventilation during high-output activities. This technical marvel weighs just 185g, making it the perfect companion for year-round adventures whether you're scrambling up rock faces or navigating snowy terrain.

The Atom Vest's thoughtful design shines in the details—from the PFAS-free DWR treatment that repels moisture responsibly to the dual hem adjusters that seal out drafts when temperatures plummet. Stow essentials in the two hidden-zip hand pockets or secure valuables in the internal chest pocket, which doubles as a stuff sack with carabiner clip for compact transport when conditions warm up. Equally at home as a standalone piece during fall hikes or as a strategic midlayer for winter touring, this versatile vest balances technical performance with everyday wearability that active women will reach for season after season.
