Vaquerillo is an old style Mexican saddle bag usually made with long haired goat skins and a harness leather backing. They hang on both sides of the saddle. Large pockets on the underside to carry tools, wire, food, etc. Vaquerillos range in weight but usually about 7lbs. (they are heavy which prevents flopping around). Length varies by skins but on average about 4ft. on each side.
