【New, Unused】 Mito Kogyo Cold Water Circulation Cooling Vest CV24-SCH For heatstroke prevention! This is a cool vest. I'm selling it because I don't have a chance to use it! Here's the official description. -------------------------------------------------- ◯ Safe and hygienic thin design, regardless of the usage environment. ◯ By inserting ice bottles (small) (large) or two plastic bottles, the balance is maintained, allowing for the attachment of a harness. ◯ 3-layer protective sheet inner for even longer cooling time (hand washable) ◯ The ice bottles have a thin design, so you can sit back in a chair without feeling any discomfort. ◯ The back tank only needs about 200mL of water, making it lightweight and allowing for long-lasting cooling, as the ice melts slowly. ◯ Hand washing is possible without removing the pump. Safe even in the event of water leakage. ◯ The ice bottles are equipped with reinforcing bars and air chambers to prevent expansion when frozen. Note: AC adapter for charging is not included. Please use a commercially available AC adapter.
