There's cheaper alternatives but I'm still a big fan of the Wolfman products. The E12 saddle bags rock. They keep the weight down low. Collapse when not needed and they have plenty of attachments to secure a sleeping bag, tent, more luggage etc.

I agree 100%. I have a full set of them (front fender bag, tank bag, saddle bags, and duffle bag). The only other bag I would consider for a "hybrid bike" would be a giant loop bag.
By Hybrid bike I mean something that's more dirt bike than adventure bike (WR's, KTMs, CRFs, etc).
