Matthew Curtis wrote a review of Nathan Speedbelt 1.5 Lumbar Pack on December 24, 2010
I like everything about this pack - you have two bottles - hwich you can fill both with water, or one with water, one with gels. There i a nice sized pouch to throw keys and some extra food or small gloves in as well. I usually use one of these with water, and the other with gel, and then carry a nathan quickdraw as well. Perfect size, and stays in place pretty well when running on any terrain - trails, downhills, etc.
