YAMAZEN DIRECT COOL Cool Vest Water Cooling Clothing 2025 Model YAMAZEN Direct Cool Premium Water Cooling Vest PRO DC-Y1 Used only twice - Brand: YAMAZEN - Model Name: DIRECT COOL - Color: Blue - Accessories: Charger, Cooling Pad - Size: Free Thank you for viewing. This is this year's model, with water cooling for the neck and armpits. The battery was used as a spare for a water cooling vest I used before, so I didn't use it very often. Because I had this battery, I purchased the vest without a battery, so the box says "without battery," but it comes with a battery. I forgot to take a picture, but I also have the freezing bottle, so it's fine. I used to use a type without cooling for the neck and armpits, but having these two areas cooled made it much easier. I have decided to use a different type, so I am selling this one. I have only used it indoors twice, so it is in good condition, but it is a used item, so please refrain from purchasing if you are concerned. I will gradually lower the price if it doesn't sell, so please wait until it reaches your desired price. Also, If there is an item for Eco-Mercari delivery after purchase, I would like to ask those who can check the agreement to purchase. I will aim to ship it as soon as possible as it still seems hot, but please allow 1-2 days for shipping. Also, it will be packed in a box and wrapped with bubble wrap. Thank you.
