Thank you for viewing. INSTINCT reflex belt, for running and trail running. Size 3, made of polyester, a combination of black and yellow. I purchased this item on a flea market site, which was bought new in 2024 and used for a trial run of about 20 kilometers, but the size didn't fit, so I'm putting it up for sale. INSTINCT products are quite expensive, so Please consider this item as it is available at a lower price than the regular price. Price negotiation is not possible.
