I'm also looking for a source for webbing/strap keepers. Much like a looploc, but with one of the long edges split so that it can slip onto the webbing (one long edge is sewn to the loose end of the webbing, the other long edge slips over the functional portion of the webbing).
My pack has a couple of these for keeping the loose webbing ends attached (instead of hanging all over the place). I'd like to add them to the other straps to clean the whole mess up.
I've checked Thru-hiker, Oware and Quest but I can't seem to find them.
