This may be the last belt you need to buy! The Men's Plain Harness Belt from Yonie's Harness Shop is made of the same material which the Amish and other horse-and-buggy-driving folks use for harnesses. This material, called Biothane, has an inner core of webbing, overlaid with polymer coating. The result is an incredibly durable strap that will not stretch with use, as does leather. These belts can be easily cleaned with water, are mold- and mildew-resistant, and will last for years!
