gotta be careful with fanny packs .... all that weigh bouncing on your hips can cause issues/wear you out. I know a rider that had some back problems caused by crashing and having the fanny pack tweak his back. I've been going back and forth from a camel back mule for everything and a standard camel back for water and a fanny pack. lately I've been thinking of how to mount stuff to the bike. But I've lost kits off the back fender and the front fender before. plus tool packs screwed to the rear fender can cause it to flex too much in rough conditions. It can also get in the way when sliding your butt over the rear fender when decending really steep stuff. I don't think the perfect solution exists. short after work rides I go with the fanny pack and camel back. All day rides or enduros I go with the mule loaded up.
