CamelBak Mayhem Hydration Pack - 641cu in
Made with durable nylon and burly zippers and a 3L reservoir, CamelBak's Mayhem Hydration Pack takes your adrenaline-crazed bike rides and rough gravel crashes in stride. Store your digital camera or music player in CamelBak's heavily padded and weather-resistant media pocket and bring home proof of your trail pandemonium. Stash an extra jacket and some bike tools in the main compartment. The Mayhem Hydration Pack's back panel ventilation system keeps you cool, and the comfortable harness and waist-belt stabilize your load as you bounce off boulders. Gear straps with quick-release buckles hold your helmet and shin guards on your way back up.
Bottom Line: Trust your CamelBak Mayhem Hydration Pack to get you through the worst of it.

Review Title
By: Tyson Bolduc
September 23, 2009
Probably one of the greatest outdoor innovations to outdoor activities in our time. Alright, maybe that is a little overzealous of a description, but this water system is revolutionary none-the-less. While keeping you a few degrees cooler with the water on your back, as well as your hands free to ride your bike, look at a map, or hold the hand of your lover while you hike, this system is ready for action. I wish the top, where you fill up the bladder, was easier to open, but just twist with all your might and you can get it open. Otherwise, this is a outdoor playtime must, but for me it is best Mt. Biking.
Change me.
