Not sure if this is at all along the lines of what you're looking, but check out Bagjack.
I have a Filson 257, which still gets the majority of use. Also have a leather case, but wanted something a bit more casual / fun. Wound up picking up an Acronym, which is made by Bagjack. Otherwise, I likely would have ordered that Next Level Messenger. I think the pricier Bagjack models use fidlock magnetic closures.
