Let's talk about Moncler's Bosona Jacket. It's light as a feather, but trust us, it doesn't skimp on the warmth. Thanks to Moncler's clever use of materials, a soft corduroy and a longue saison lining provides protection without adding weight. Plus, it's got a pull-out hood and adjustable cuffs and hem so you can change up the fit and really seal out the chill.
