The product description provided by AI states that this is a piste, but it's not the typical "shaka-shaka" material. In my personal opinion, it feels more like a thin jersey. Price negotiation is possible. Please feel free to consult. The following is the product description provided by AI: Blue piste made by Mizuno, with the Tokushima Vortis logo, size L. - Brand: Mizuno - Team Name: Tokushima Vortis - Color: Blue - Size: L - Logo: Pocari Sweat Thank you for viewing. The Tokushima Vortis emblem on the left chest has some peeling (photo 4). The POCARI SWEAT logo on the chest has some lifting and peeling (photos 2, 7, 12, and 13). There is some fraying on the back of the left sleeve (photo 10). As this is a personal inspection, there may be oversights. If you are looking for a perfect item, or if you do not understand used, vintage, or pre-owned items, please refrain from bidding.
