Comfort improvements like Thermal Zone Distribution provide everyday wearability, and the Cosima also comes feature-loaded for optimum performance. 2-way stretch REPREVE fabric and Full-Motion articulation allow a full range of movement, so youll be at your best on the slopes. Of course, when off the slopes, the chic Cosima is guaranteed to keep turning heads.

About the Obermeyer Women's Cosima Down Jacket

The Obermeyer Cosima is a women's hip-length ski jacket with a down and synthetic blend fill, a two-way zipper, a powder skirt and thumbhole cuffs. It is built for cold, snowy days on the mountain and still works for everyday winter wear. Its warmth and snow-sealing features draw high marks from owners, though some find it bulkier and shorter than they expected.

    Questions and answers

    Is the Obermeyer Cosima warm enough for skiing?
    Yes. It uses a down and synthetic blend fill and is rated for the coldest conditions, with a powder skirt and sealed cuffs for snowy days.
    What size should I order?
    The jacket comes in alpha and numeric sizes on a regular fit, and the size chart lists chest and back length. Check your chest measurement against the chart before ordering.
    Does it have a powder skirt and vents?
    Yes. It has a powder skirt, adjustable cuffs, thumbholes and a two-way zipper that can be opened for ventilation.
    Can I wear it around town, not just on the slopes?
    Yes. The sporty hip-length cut and everyday colors work for commuting and errands, and the powder skirt can stay out of the way.
    What is the fill made of?
    The fill is a down and synthetic blend, and the shell uses recycled materials with a 100% nylon lining.
    Is the Cosima a good value for a down-blend ski jacket?
    It pairs a down and synthetic blend fill, a powder skirt, thumbhole cuffs and recycled materials, which is a solid feature set for a mid-range ski jacket.
