Made of 12 ounce U.S. made veg tanned leather, the Rich Phillips Cycles Harley Tool Roll will always hold its shape. Sewn with thick nylon thread, it measures 10" by 7" by 4" deep. Because of the special way that the front and back are sewn together as one peice, it is alot less likely that it will ever lose its shape. Some bags are made with reinforcements to bolster up their thin leather. This leather is so thick that it does not need any reinforcement. Most Harley Davidson made bags are made of cheep vinyl. This tool roll bag is sealed with a beeswax based waterproofer, "aussie leather conditioner". It is used to bring out the richness in the grain and color.
