Great Hydration Pack
The M.U.L.E. has worked great for me, although not using it for biking I have taken it on many trips to Jackson Hole and to Fremont Canyon. It works great for boarding, packs everything I need for the whole day snacks, ipod, holds shedded layers, etc. Also works great for a short hike to the crag unless i need all of my gear in which case the bladder just pops out and fits right in my larger pack.
