It’s reversible, featuring a cotton-nylon “Tamamushi” shell on one side and rabbit fur on the other. Among all the vintage garments I’ve seen so far, I feel this piece ranks among the very best in terms of the quality of its reversible design. When worn as a bomber jacket, the rabbit fur serves as both the bomber collar and the lining; when flipped inside out, the fur that was the bomber collar transforms into a stand-up collar. The fact that no fur is used on the sleeves not only makes it comfortable to wear but also enhances the design when the jacket is flipped inside out.
