In most cases a runner has some stuff to carry. Unfortunately runner cloths are often not equipped  with pockets. The question is where should I put energy bar, a drink, key, authentication. card, smartphone and the whole household? And do we feel bothered by having all the stuff in one pocket?

A running belt is a clever solution to carry all the stuff. It provides several stretchable pockets. During a run we can easily finger out all the things. The running belt keeps warm and it is machine washable. The wear cloth is quite heavy but on the other hand resistant and ideal for training purpose. The cloth seems to be manufactured in high-quality.
