Hands-free is the preferred method for a lot of runners and a vest/pack can be overkill for many shorter runs or races. This belt is soft and comfortable and minimizes the chance of chafing with new fabrics and design. Weighing in at just 7.6oz (73g) it keeps a low profile. It comes with a 500ml Body Bottle and will carry most soft flasks just fine. This belt will also carry a few gels, your phones, and a key no problem. Pair with the Adventure Pocket to carry more nutrition and this is a great kit for ultras.
Fit: S/M: 26-33", M/L: 31-40"
