Round cotton gym bags are a unique and stylish alternative to traditional duffel bags. They are typically made from a heavy-duty cotton canvas, which is durable and breathable. This breathability is a plus for sweaty gym clothes. However, unlike traditional gym bags made of nylon or polyester, cotton gym bags may not be water resistant.
These round gym bags come in a variety of sizes, but a "long" round gym bag would likely have a diameter exceeding 18 inches and a depth exceeding 12 inches. This size is large enough to comfortably hold all your gym essentials, including your workout clothes, shoes, water bottle, towel, and toiletries.
