This is the Ice Harness Sports, the top-of-the-line model of Akagi Kogyo's Ice Harness. I purchased it new in the summer of 2025 from the official Rakuten shop. Unlike the regular model, the fabric is sports fabric, providing a cooler and more comfortable fit. Many inexpensive imitations are available, but this is a genuine product made in Japan. The color is simple black, and the size is S. I am 160cm tall and of average build, but I bought the S size because it is written that the cooling effect is better when it fits snugly to the body. (For women, unless you are very large or very plump, S seems to be the best size. The size can be easily adjusted with the Velcro on the front, so you can make it larger than the size indicated. I think M size would have been too big and wouldn't have fit, as it's a unisex size...) Many imitations are available at low prices, but I haven't tried them, so I think there may be differences from the genuine product in terms of the duration of the ice packs and the sewing quality. I used it twice for work, but I was provided with an alternative, so I no longer need this. I would like to sell it to someone who needs it during the scorching heat. For those who enjoy sports even in the heat, those who have outdoor work on a daily basis, those who cannot wear a fan vest in a scorching workplace, and those who want to get even more cooling effect by using it with a fan vest. It comes with straps for a better fit and a set of 4 dedicated ice packs (I used a different ice pack for the back, so 2 for each side x 2 times for a total of 4). The entire set cost over 10,000 yen when purchased new. It has been home-cleaned. Thank you for your consideration. Ice vest Cool vest Summer vest Cooling Fan vest Cool wear
