FLIPBELT Elite - Size S - Color: Black This model can be put on and taken off with a side zipper. There are three pocket openings (one with a zipper). It has a lot of storage capacity for smartphones, keys, gels, etc. Non-slip processing is applied to the inside, so it is unlikely to slip off. Size: S size * Because it is an American size, we recommend choosing one size smaller than your usual Japanese size. (According to the manufacturer's published values, size M is about the same size as L in Japan.) I used it with a waist of 80cm. The fabric stretches a lot, so I feel that people with a waist of about 70cm to 85cm can wear it. I used it while running, but I am selling it because I have fewer opportunities to use it. How about it for running and walking during the upcoming full-scale marathon season? The following is the manufacturer's description: The FlipBelt Elite is the top-of-the-line model with various premium features such as a water-resistant zippered pocket and a side zipper. It is ideal for those who run seriously and those who want the best running belt for any activity. It has a semi-lock zipper on the side, so you don't have to worry about the zipper opening unexpectedly, and it can be put on and taken off quickly. You can secure your keys with the elastic key hook and put your valuables in the water-resistant zippered pocket. In addition, the inside of the belt is non-slip, so it won't move even when worn over slippery clothes. In addition to the reflective logo, highly visible 3M reflective material is used on the upper and lower edges of the belt.
