This is the Speardiver spearfishing gear bag with PVC coated mesh. I've been using this bag for 4 years and really love it, anyone that's been with me diving will remember I always have this bag. All my gear goes in there except for the fins and speargun.
There are many waterproof bags out there. For my kind of diving I don't see the point of the waterproof bags. The mesh bag goes on the boat with me. At the end of the day all the wet stuff goes inside, by the time we get to the dock all the water is drained out and when I put it in my car there isn't even a wet spot on the carpeting when I get home. For my stuff that needs to be dry like car keys, cash and cell phone I have a small waterproof box that I keep inside this bag.
The rubberized mesh is really durable. Even sharp objects like a stringer don't catch in the mesh and don't tear it. The bag has an outside pocket with velcro closure where I keep small stuff that I don't want tumbling around inside like a whistle. There are other similar mesh bags but not all are made equal. This one is really top notch and durable. At 29" it's also 1" longer than others.
