This top quality natural canvas Puerto Rico cinch backpack is a refreshing change from the common, cheaply made, nylon cinch pack. Featuring rich, vibrant colors, these cotton Puerto Rico drawstring bags are perfect for the gym, travel, a change of clothes, or a pair of shoes. Broad Bay Cotton Puerto Rico Flag cinch packs are fully lined, and feature a secure zippered pocket as well as a large drawstring closure main pocket. Wide adjustable shoulder straps are a vast improvement over thin shoulder biting strings common on many other cheap nylon Puerto Rico drawstring bags. 17.5 in high x 14 in wide laying flat.
