When winter's bite demands your warmest armor, the Arc'teryx Atom SV Jacket delivers uncompromising insulation for women who refuse to let cold weather derail their alpine adventures. This technical powerhouse combines Coreloft™ 120 synthetic insulation with female-specific thermal mapping that keeps your core toasty while preventing overheating in high-output zones like your underarms. The wind-resistant Tyono™ ripstop face fabric shrugs off everything from tree branches to ice crystals, while articulated patterning and stretch panels move with you through every crampon step and ice axe swing. Whether you're wearing it as a standalone piece during winter hikes or layering it under your hardshell for above-treeline missions, this jacket's regular fit and thoughtful design make it the cornerstone of any serious winter hiking kit that performs when the mountains get mean.
