The FlashFlo hydration waist pack supplies as much water as a two-bottle fanny pack, making it a great accessory for runners and walkers on the go. The pack is built around a 1.3-liter Omega reservoir with a drinking tube that pins to your shirt, so you can grab a quick sip whenever you need a boost. Joggers will also dig the external zip pocket, which stores such items as keys, wallets, and other valuables.

Thanks to the secure outer pocket–which holds a CD player, MP3 player, or iPod–you can listen to your favorite tunes while you jog. Other details include a breathable mesh waist belt that fits comfortably around your midsection–a must for hot days–and reflective striping that helps increase your visibility in low-light conditions. Stable, cozy, and large enough to accommodate a one- to two-hour run, the FlashFlo is backed by a two-year warranty (with a lifetime warranty on the Omega reservoir).
