Features In addition to black, the theme color of LANTERN, the Military Boa Fleece Blouson is available in foliage (military green), which symbolizes the U.S. MILITARY. Based on the military fleece of the U.S. military, the silhouette, the texture of the boa, and the coloring have been carefully selected to create an original long-pile boa fleece that is soft, light, and extremely comfortable to wear. The design, which incorporates nylon taslan to prevent wear and tear on the areas that are easily rubbed, which is also a detail of military fleece, is not only functional but also provides a subtle two-tone color accent. By eliminating the shoulder line, this item incorporates functionality and design that ensures a wide range of motion into modern fashion. Visron ZIP is used for the front and chest pockets. The inner pocket has been upgraded to be more functional, based on the LEVEL7 pocket of military outerwear.
