We have perfected our tumbling capability over the last 20 years and now offer it as an additional service when you purchase a vest. What started out as a science experiment, turned into a mission to develop a tumbling machine that could replicate years of wear in 1 hour of tumbling. We will never share the specifics of our machine, however we will say that we have the best damn vest breaking in service in the USA and most likely the only machine out there! Many customers looking to purchase a leather biker vest want their "cut" to have a broken in feel and aged look rather quickly. We have perfected our antiquing tumble method designed to further bring out the vintaged look in the leather. The end result is a motorcycle vest that has been well worn for about five years.
