Not going to pay to 'convert' to the QR types (Topeak, Racktime), but also don't want the attachment straps to be velcro, either. I'd prefer something with buckles. Doesn't have to be water tight, nor overly large. Just big enough to take the bike specific gear out of my backpack- lights when not in use, batteries for said lights, gloves, safety vest, safety goggles that I plan to get that fit over my glasses.

Any ideas?
