the diveshop i work at sells akona, its our best selling bag, most of our staff has owned or used other brands and have switched to Akona. Most of us use the Akona Deluxe Backpack, works great. The security sleeve you're talking about is a separate nylon bag that has no markings on it, all black, that your bag slides into. looks like a large duffle bag then. Akona is one of the best selling bags because its appearance is less inviting to airport theives and vandals. Most people recognize other larger brand names for diving equipment, than Akona. The logo on the bag for Akona as you well now is the frog, but underneath it says Adventure gear, unlike other companies that advertise a scuba name. Since our staff has changed to Akona brand bags we've had less problems in the airports with missing items, or damaged items. Hope this helps.
