Nathan Elite 1 Plus Waistpack Great pack; bottle not so good. By Phil the Runner from Washington, DC on 9/19/2010 3 out of 5 Pros: Comfortable, Stable, Highly Adjustable Cons: Poor Construction, Leaky Valve Best Uses: Running Describe Yourself: Casual/ Recreational What Is Your Gear Style: Comfort Driven Was this a gift?: No The belt bag fits well and is easily adjusted. It keeps everything in place and has room for energy bars and keys without feeling too bulky. The bottle that comes with the bag, however, is poorly designed. After only two months of use, the valve and the finger hook all came apart in the middle of a run. I would recommend the bag to anyone, with the caveat to purchase another water bottle. ( legalese )
