This jacket is a work of art. Each jacket is hand cut and the design is stitched into each design piece by piece. This jacket is extremely comfortable, breathable, warm and packable enough to stuff in your backpack. The exterior is super soft and durable nylon with a coat of water repellent just in case you get caught in a storm. The insulation is Primaloft gold 200gm and shearling lined to keep you warm without weighing you down. Get ready to turn heads all over the mountain. Staying true to the Aviator Nation brand these jackets reflect the retro California vibes we are proud to call our own. They're handmade in LA with imported materials. This jacket runs true to size to the rest of the Aviator Nation collection. We'd advise getting the same size in the jacket as you would a hoodie. Size tag has been removed so please refer to the measurements in photos. For reference, I usually wear an l/xl top & this fits snug of me.
