We were the first brand to provide a reusable mesh bag with a wetsuit purchase that you can use in the real world. Athletes constantly ask us for an additional mesh bag so they can haul their gear from home to water and back again. This mesh bagis approx. 18" x 18"and was designed to be worn like a backpack for transporting a wetsuit, but also works great for carrying a towel, pool equipment or a change of clothes. Quality, breathable mesh with a blueseventy patch on both sides. Pulling on both strings closes the top from items falling out. 100% polyester.
