The Shortrail III belt bag fits perfectly on your hips and is also adapted for longer training sessions. You can easily store your valuables in the sophisticated pockets and keep your belongings safe with you, which is a requirement for long runs. It is equipped with a main pocket where you can store a backup windbreaker or a vest, which will come in handy in case of bad weather, as well as a 1.5l hydro bag (the hydro bag is not part of the package). You will certainly also appreciate the key clip, loops for attaching trekking poles or jacket and two side zip pockets for e.g. a phone or an energy bar. The loincloth has an adjustable waist belt, reflective details for increased visibility, is very breathable and made from 100% recycled material.
