BEAMS 100 Masterpieces ✨ BEAMS PLUS MIL Type N-3B Down Primaloft This is the N-3B down jacket from BEAMS PLUS. I bought it last year. I wore it once and stored it in the closet, but upon inspection for the listing, there was a scuff on the button part of the left pocket (photo 14). Otherwise, I think it's in like-new condition overall. Based on the "USAF" aircrew heavy zone jacket N-3 series, manufactured from the late 1940s to the 1970s. This piece updates the functionality of the 1950s "N-3B," commonly known as the black tag. ・The front has an adjustable double zip and loop buttons. ・The front placket attached above the front zip prevents cold air from entering. ・The oxygen mask tab has been updated to a hidden pocket. ・Hand warmer pockets, the neck, and the inside of the hood are lined with boa for improved cold protection. ・Hidden ventilation function under the arms. The silhouette is roomy, with ample width and shoulder width, allowing you to enjoy coordinating with various inner layers. Outer fabric: Heavy nylon twill Filling: ALLIED FEATHER DOWN / 650 fill power down SIZE: S Color: sage olive, khaki
