L size black waist belt made of polyester. - COLOR: BLACK - SIZE: L - MATERIAL: Polyester - COUNTRY OF ORIGIN: MADE IN CHINA Thank you for viewing. The above was written by Mercari AI. I bought a waist pouch for a marathon, but it was too tight around the waist and didn't fit. I opened it once and tried it on, but put it back immediately. It's a convenient pouch for running and walking. The waist is elastic, so there's no band, and I think the items in the bag won't wobble around. I bought it hoping for that effect. My waist is 90cm and it was tight. It felt like I could still use it, though.
