This uniquely designed flexible mesh-backed cinch bag backpack is the perfect bag for books, a change of clothes, a pair of shoes, or a towel for the pool or beach. The front features sophisticated-look microfiber fabric while the back is a super strong stretchable mesh. The zippered compartment is fully enclosed, but the large mesh main section allows air-flow to let your shoes, gym clothes, or wet towel dry out. This great drawstring bag also has reinforced grommets for strength and durability, and an oversized cinch drawstring cord for comfort. 18” high x 14.5” wide laying flat.
