It packs a lot in. In terms of its specs, the Road Runner Bags fanny pack isn’t all that big: 10 by 5 by 2 inches, with a capacity of 1.6 liters. But because of its rectangular shape, thin material, and basic main compartment, which has just one internal flap pocket, it can hold about the same amount of stuff as the physically larger and trapezoidal Herschel Pop Quiz Hip Pack (13 by 6.5 by 3.5 inches). During testing, the Road Runner Bags fanny pack had enough space for a small paperback, a wallet, a smartphone, keys, and a snack-size bag of chips. Some testers found it bulky to wear, especially when seated. And since the heavy-duty Cordura material isn’t very pliable, it can feel uncomfortable when the pack is full.
