An ultra-light, lumbar reservoir-based mountain bike pack that repositions the water weight on your hips for maximum stability and comfort. The Volt comes with an Antidote Lumbar Reservoir with 1/4 turn - easy open/close cap, lightweight fillport, patented Big Bite Valve, HydroGuard technology, PureFlow tube, easy-to-clean wide-mouth opening. Also features ultra-light materials, lumbar reservoir compression, a bike tool organizer pocket, and stretch overflow storage.
I have been using this pack for about 6 months. The side pockets are very convenient. It saves me from taking the pack off to get to some essentials (I keep gels, cliff bars and a multitool). In the summer I put an extra hydration pack in the area behind the first set of pockets and it works great (I keep water in the main reservoir and gatorade in the other). The position of the reservoir is very comfortable and I don't ever notice it on my back.
