We have sold a ton of the natural horsehide so far. The reason I did this belt is:
1) I have not seen horse hide used much in the current market, especially for a belt, and I wanted one to offer for our customers
2) I love how horse ages. It tends to have a more grainy appearance, and thus more variation and natural markings that develop as it darkens.
3) Horsehide is stiff, but can be thinner compared to cowhide and just as durable.
4) We were able to offer them at reasonable price.
I am not a real leather guy, so any of you real leather people can probably give a better description and more details. These particular belts have not been out long enough to see any serious aging, but it is natural horsehide and a Google search should show some photos of some items.
As for the design, I wanted a single buckle solid brass style in a 1.5" width is the right size for denims to fit nicely through belt loops. Too many roller buckles out there right now, I prefer a one piece buckle if I have a choice. The 7 holes at a 3/4" width and the 4 set reverse rivets is Dustin's design, which is easier to size and looks great and really durable.
The other two colors are Chromexcel which speak for themselves.
