I'm looking for a backpack that I can use for day long bike rides/hiking. I've been looking at the camelbak mule since it can carry 3L and does a good job of not shifting around and is portable.
I'm assuming this isn't my cheapest option though. Are there any small packs like the MULE that are good for carrying a days worth of supplies and wont shift around? More importantly, a pack that's cheap?
