I looked it up, it's a type of leather, not the color:A Guy posted a pic of his boots in this leather is gorgeous and wondered if they are bringing it back... apparently is not available in the options at the Nicks Site...
Latigo leather is cowhide leather that is combination tanned. First it is chrome tanned, then it is vegetable tanned. Before modern combination tanning, latigo had been combination tanned with alum and gambier.
Latigo is usually infused with oils and waxes. Techniques such as hot-stuffing, wet-stuffing, and fat liquoring have been devised to increase the amount of oil and wax the hide can hold. Due to oil/wax infusion, and its partial chrome tanning, the leather is moderately flexible, less rigid than full vegetable tans, but more rigid than full chrome tans. Because of its weight and tanning process, latigo is among the most expensive cattle hide leathers.
Seems like a best of both worlds kind of thing
