Size: L Length: 66 cm Width: 63 cm Sleeve Length: 92 cm This item is larger and more relaxed than a typical L size. This is an N-2B jacket, a collaboration between Alpha Industries and Helinox. Based on the N-2B flight jacket, this reversible jacket features flight nylon and warm boa fleece, allowing you to enjoy two different styles: military and outdoor. The arm features a special name tag commemorating the collaboration, and the iconic shoulder pocket is removable with Velcro, making it reversible.
