Yeah, those are cool latches. Don't know if they're rated "bear proof", but they're darn close. Watch a newbie try to figure them out sometime.
The way the boxes latch into the frame on our Sotar is one of the things I like about it the most. The "beavertail" stern section of the frame is kinda odd though. Borderline PITA unless you have a ton of straps. It is a frame from '03, so they may have made changes since then.
