Instinct's reflex bel M size (79-86 cm). You rarely see this in Japan. I bought it at Trippers. It was a little small for me, so I'm reluctantly putting it up for sale. I only tried it on, I haven't actually used it. From the website below: This is a wide and exceptionally storage-capacity waist belt that doesn't sway easily. You can store bottles and poles, so you can use this for short races! Features: ・6 pockets ・Small item pockets on the front ・Large pockets on the front and back that can hold a jacket or a 600mm soft flask ・Pole storage space on the back ・Integrated race bib holder ・Excellent elasticity, quick-drying, and breathability ・Loops attached to each pocket for easy identification of the pocket opening
