Thank you for viewing. This is a diving bag from AQUA LUNG. It's a durable nylon bag with a user-friendly design that includes mesh pockets. 【Specifications】 ・Color: Black ・Side Pocket: 1 While there is some wear and tear, it's still in good condition and can be used for a long time. Please check the photos for details on the condition. My father has retired from diving, so I am listing this on his behalf. I do not have expert knowledge, so I cannot provide detailed information. Please check the photos for the condition and included items, and purchase with your understanding. If you have any questions or would like additional photos, please feel free to comment.
