I have had a Stahlsac Bonaire mesh backpack for almost 3 years now. It is huge. Big enough to hold my and my ex-'s gear at the same time. I.e. 2 x BCDs, 2 x wetsuits, 2 x pairs of fins, etc.. I am still constantly amazed that it has held all that stuff - wet! - on more than one occasion for carrying back and forth between boat and dock/car and it still does not have any rips or tears. That is including my stainless steel back plate and wing rig, too, as my BCD. And, numerous times, also 4 x 1# weights that I usually keep in my bag. It is amazingly strong. And yet, once I've pulled everything out, it takes up almost zero room under my bench on a boat.
