Thank you for viewing! This is a gray fan vest set with a cooling function, perfect for comfortable heat対策 (heat countermeasures). - Product Name: Fan Vest Set - Color: Gray - Brand Name: TANOKA - Function: With cooling function - Number of Pockets: 2 Unisex There is a zipper at the collar. You can put in ice packs, etc., to cool your neck. It will be cool. * Battery-powered battery is also included. According to the instructions, the fans are separate, but I will send them as a set, so you can wear them immediately (operation confirmed, see photos 9, 10, 11, 12). The fan strength can be adjusted in 3 levels. I bought it to protect against the heat at a summer festival, but I didn't wear it because it rained.
