This duffle bag was built from 5-6oz oil-tanned American cow leather. The oil-tanning process gives a rugged and durable finish, one that not only looks great but provides years of protection to whatever you stash inside. The roll top enclosure allows for expansion when you need more room. The perfect sized bag for your weekend getaway, gym outings, or when you want to haul somethings around in style. Carry your goods in a bag that you know was handmade by artisans in Boston using the finest American-tanned leather.
