Obermeyer Cosima Jacket - Women's Insulated Ski Jacket for Warmth, Performance & Everyday Mountain Style

The Obermeyer Cosima Jacket is one of those ski jackets you'll look forward to wearing every time the snow starts falling.

Featuring body-mapped insulation, stretch fabric, and ski-specific features throughout, the Cosima keeps you comfortable in changing mountain conditions while allowing you to move naturally from first chair to last run. It's a jacket built for women who want dependable performance without sacrificing style.
