With all the debate about the spring and fall leathers, I took a photo of the spring metallic goatskin flap and fall deerskin bowler side-by-side, as well as the flap on my shoulder. It's a super comfy bag! The deerskin finish is more matte than the goatskin, especially IRL. I couldn't imagine the flap in the deerskin leather though; it was made for the metallic goatskin. This bag could go from dress down to dress up much easier than the bowler, which I feel has a more casual shape. Click on pic to enlarge photo - I made them too small.
