Query: Great All-Outdoors Bag

I got into Mtn. Biking this year and wanted a pack to carry all my essentials plus hydration while on the trail. I looked at different models but always kept coming back to the M.U.L.E - this pack's got the best combination of features I've seen in similar mtn. biking/hiking packs. The 3L bladder is more than enough for several hours of outdoor activity. When I buy packs/bags of any type I always look for sturdy construction on the straps/handles. The straps of the MULE are nice and wide so they feel comfortable even when the bag is fully loaded. Double zippers (except for the pocket that holds the bladder in the back) and waterproof tabs that cover the zippers similar to those found in technical jackets give you piece of mind the water won't go into the bag. The iPod/small electronics pocket in the top has a waterproof zipper. Overall, this pack is solid for any outdoor sport you take it on...
