I may commission another custom horsehide jacket and this one I'm considering asking for two layers of lining in the sleeves. An inner layer of wool for warmth and an outer layer of rayon so my shirt sleeve doesn't ride up. Is there any reason I wouldn't want two layers in the sleeves? On leather jackets lined with wool in the body and rayon in the sleeves, I notice there can be a chill on my arms and I'd like to avoid that in my next jacket. Any thoughts, guidance, experience???
