I bought one of these to go with the same style saddlebags, and it really comes in handy on a longer trip. I have even been able to stow my leather in there when it was too hot to wear, and I wear an XXL, so there's a good amount of space inside. It mounts easily and neatly to the bike, via the luggage rack underneath the pack and the velcro strap around the backrest. If you don't have both, you really can't use this (well, maybe, but it would be difficult.) Good styling, overall. The synthetic leather doesn't look bad, and the straps and buckles are pretty good, as well. It's pretty sturdy and rugged feeling - not cheap at all. If you want a decent item to store a little bit of extra stuff, this one is a good choice.
