Using a combination of hydrophobic goose down and Omni Heat synthetic insulation, the Columbia Men's Platinum 860 fill Turbodown Jacket provides the loft and warmth of down with the moisture management of a synthetic fill jacket. Within each baffle is a stacked combination of natural and synthetic fibers. While the down maintains warmth, synthetic fibers offer breathability and pull moisture away from your body. The Omni Heat reflective lining uses small reflective circles along the face of the fabric to reflect your body heat back to you, and the micro ripstop shell helps keep all that techy fill inside the jacket. Great for cold days on belay or hikes into the alpine, the Platinum 860 is an essential jacket for any adventure.
