That works

The aluminum, TIG welded frame is surprisingly light, and it actually provides much better ventilation than youll find in most internal frame packs (Though Osprey has made great attempts to bring this back.) Much of the strapping and suspension on these types of packs is attached to the frame via cotter pins and through tension (applied with cordage, as seen behind the hip belt.) The bottom of the pack straps attach onto some serious U-shaped aluminum anchors that pivot on the frame

However, a well-organized tackle box doesnt just happen by accident it all starts at home base

I think that probably has to do with its orientation when its swimming coupled with its narrow and smaller overall profile
