But that's not what makes this Super Tank so useful. This is perhaps one of the biggest and best designed back packs you'll see. Complete with a dozen pockets - even some of the pockets have pockets! There is a main large zippered compartment, that easily held an extra large sweat shirt and a couple of tee shirts (trying to stuff it to look good for the photo. the next pocket down is almost as big as the first, then below that there is a handy pocket with a couple of internal velcro and a mesh zippered pocket, then there is an expanding mesh pocket area great for goggles, a cycling helmet or tennis racket, next there is a handy smaller pocket that has 2 internal mesh pockets to keep stuff snug, and finally each side has a mesh pocket. We congratulate you if you can figure out enough stuff to take with you on a ride to fill the pockets.

As a test, we gathered up a bunch of typical supplies that you may consider taking with you on a ride - tire patch kit, compressed air or pump, duct tape, jacket or sweat shirt, ipod, phone, sunglasses, and tried to see how well it fit. We easily fit everything and had room for more. The point is, this thing is huge, versatile and surprisingly comfortable and is the perfect companion to any ride. If you're doing longer rides, you can pack in enough stuff to turn a potential disaster into and adventure that you'll joke about around the fire at night.
