This is a novelty item: a dry mesh fabric top that was distributed to professional license holders at a diving event in Asia several years ago. The color appears black at first glance, but it can also look like a dark navy blue depending on the light. It is new and unused. I opened it from its transparent bag for the photos. It is a unisex L size.
