Running back made by Body Maker. It's a design from RUN de Mark, a running community that Mr. Tetsuhiko Kin was involved with. It can hold a water bottle, a towel, and a smartphone. It's very light, so you can pack it in your bag for running while traveling. The size is free and adjustable. Thank you. Harness-type running bag that provides a comfortable fit with breathable mesh material. - Brand: RUN de Mark - Colors: Orange, Black - Material: Mesh - Features: With pockets - Design: Harness type Thank you for viewing.
