Love your reissues! The charcoal gray reissue is made of metallic sheepskin I believe. I have the same bag in mini and I love it. Chanel did a great job with that series, wish they would bring back sheepskin again!
Thanks and also many thanks for reminding me! You're 100% right that these were sheepskin, think the chevron might have as well. I also hope they bring back the sheepskin and other fabrications. The reissue is such a great style, especially in the mini.
