Because my jogging shirt and pants have no pockets, I decided to buy this fanny pack to hold my cell phone and house key. It's very sturdy in construction and the belt length adjuster is easy to use. The size of the pack is small, but that makes it very light weight. The small size also means it can't fit a water bottle, unless you can find a really small one. It is ideal for holding a few small items, like a cell phone with keys and some cash. The triangular design gives it a decent balance when worn around the waist comfortably, especially when jogging. I would definitely recommend it for light duty purposes.
