The Inov-8 Unisex Race Belt is a great running belt for two reasons. The first is that has better storage capacity than a slim running belt. The second is that it compliments a larger running rucksack well - if you need more storage capacity.
Specifically designed to help you to carry your running/walking poles with ease. Two strips of elastic will hold your poles securely in a horizontal position.
A zipped pocket is perfect for carrying a phone and other valuables. Gels, bars, or a small soft flask can be stored in the side mesh pocket.
This Inov-8 running belt is ideal for runs when you definitely need to carry equipment, but running with a rucksack would be overdoing it.
