Down where it counts.
The Cosima Down Ski Jacket is Obermeyer's hybrid approach to resort warmth, blending 550 fill power duck down in the upper body, top sleeves, and hood with synthetic insulation in the lower body, side panels, and underarms. HydroBlock Pro fabric adds 15K/15K waterproof-breathable performance with 2-way stretch, so the Cosima moves with you through moguls and groomers without binding up. CZV Control Zone Ventilation places mesh-backed underarm vents where heat builds fastest, letting you regulate temperature without stopping to layer down. An integrated Snap-Away powder skirt with gripper elastic seals at the waist, hook-and-loop tab cuffs with inner thumbhole gaiters close the wrists, and a removable drawcord hood with 2-way adjustment rounds out the fit system. At 26 in center back length in a regular fit, it provides full coverage in a silhouette that sits cleanly over a ski pant.
