The thisisneverthat Work Bomber Jacket is a lightly insulated outerwear piece built from a cotton-polyester blend shell with a full cotton lining and 4oz polyester fill for added warmth. A garment-washed finish gives it a relaxed, broken-in character, while a corduroy collar and relaxed fit make it as comfortable off the trail as on it. YKK #5 metal zip closure, elastic hem and cuffs, an exterior zip pocket, and an interior welt pocket round out the utilitarian construction.
