We make our jackets and vests out of 1.2-1.4 Genuine Front Quarter Horsehide, horsehide leather is tremendously dense and non-porous. Until the end of the 1930's, this was the leather of choice for its extreme durability. The density and non-porous nature of horsehide make it durable, but it is also the reason that horsehide does not dye evenly. If multiple items are made from horsehide, there is a very good possibility that each piece will have slight color variations. These color variances and the markings of the skins are considered part of the natural beauty of horsehide and reassure its authenticity. Horsehide has many unique properties, it is immensely strong and durable even in the extreme conditions and, unlike other hides horsehide is naturally waterproof.
