I have an H1. I use it to carry my digicam, tripod, usb cable, spare batteries, manual, and a few other goodies. It's tough as nails and takes a lot of punishment. Still looks as new, too. I added a single strand braid paracord loop for a grab handle.

My one wish for this pack is that it be outfitted with D rings on each side to allow for the addition of a shoulder strap...
