CamelBak M.U.L.E. Hydration Pack Review
The Camelback MULE is not too heavy, but there are certainly lighter and smaller hydration packs out there. I prefer the MULE because of the 3 liter water pack and the extra space. I keep a few emergency tools, a pump, space tube, etc in it at all times. Plus, it's big enough to have extra space for more things on longer rides. And I generally like taking some extra water with me. I almost never drink all 3 liters on most rides, but I still like the peace of mind that comes with bringing extra water. You never know when you might need it, and I have extra to share with others if needed as well.
