The piece is filled with 3M Thinsulate professional-grade KL250 high-loft insulation (450g+ in total), a melt-blown synthetic wadding whose warmth is stated to be 1.5 times that of down, and it is finished with a recycled semi-dull nylon shell over an inner lining that helps prevent the filling from escaping. The shoulder area uses an armor-style paneled construction, and the short, wide, relaxed silhouette is detailed with a YKK zipper, flap pockets with custom magnetic closures, 2x2 custom ribbing at the hem for durability, and curved sleeve shaping with gathered pleats for added texture. The thick, warm build and cleanfit, fashion-city casual styling make it well suited to relaxed everyday wear in cold weather, and the solid black color keeps it easy to layer.
