Premium Warmth Meets Mountain-Ready Performance

HydroBlock PRO 15K/15K Protection: A waterproof rating of 15,000mm and breathability rating of 15,000g/m²/24hr help keep you dry and comfortable through snowfall, changing temperatures, and active days on the slopes.
550-Fill-Power Duck Down: Premium Allied Feather & Down insulation provides lightweight, effective warmth throughout the upper body, upper sleeves, and hood for cold mountain conditions.
Thermal Zone Distribution: Strategic insulation mapping combines natural duck down with 115g synthetic insulation in the lower body, side panels, and underarms, balancing warmth, mobility, and a flattering fit.
REPREVE Recycled Stretch Fabric: A two-layer polyester shell incorporating 45% REPREVE recycled polyester offers comfortable two-way stretch and dependable protection from winter weather.
Full-Motion Articulation: Ergonomic construction and stretch lining panels support natural movement when skiing, reaching for poles, and navigating changing terrain.
CZV Control Zone Ventilation: Strategically placed ventilation allows excess heat to escape, helping regulate temperature during active skiing and changing weather conditions.
Adjustable Removable Hood: Customize coverage and protection with an adjustable hood that can be removed for a streamlined look when additional weather protection is unnecessary.
Water-Resistant Powder Skirt: A Snap-Away powder skirt with a gripper elastic hem helps prevent snow from entering the jacket during powder runs and active winter adventures.
Comfort-Focused Construction: A fleece-lined collar, fleece chin warmer, interior wind guard, adjustable cuffs, and thumbhole inner cuffs enhance warmth and comfort.
Convenient Mountain Storage: YKK AquaGuard zippers, zippered handwarmer pockets, a chest pocket, dedicated pass pocket, and interior electronics storage keep essentials organized and accessible.

Designed for Cold Ski Days and Mountain Resort Living

The Obermeyer Cosima Down Jacket is ideal for women who want premium insulation and reliable weather protection without sacrificing mobility or style. Its combination of down and synthetic insulation provides warmth where it matters most, while breathable stretch fabric and ventilation help maintain comfort through long days at the resort.

Whether carving groomed runs, riding chairlifts in cold weather, exploring snowy mountain villages, or relaxing during après-ski, the Cosima transitions comfortably between active mountain performance and everyday winter wear. Its contoured design creates a refined silhouette while maintaining the layering room and freedom of movement expected from a technical ski jacket.
