I'm looking for a back pack to wear while on my motorcycles (typically my '78 CB400). What I'd like is something like the Hamarhead Industries Day Pack: but it's a 2-month wait when you order one. Does anyone know of something similar in function and looks that can be bought off the shelf. What I like about the HHI pack is it's got a large open compartment so you can carry a variety of things, rather than just flat rectangles, the fold-over flap for keeping things dry. It's basically a sack, which is more simple/versatile than most motorcycle packs I'm seeing. I've looked into having something similar made - pretty much the same wait time. Any ideas?
