ICEMAN PRO X backpack equipped with a cooling pipe system. - Model Name: ICEMAN PRO X - Included: Backpack, cooling system - Cooling Function: Cooling pipe system - Connection Terminals: Power connection terminal Thank you for viewing. ICEMAN VEST PRO X Water Cooling Clothing ICMPX-BLV-SET Black 2024 Model Yama-shin Full Harness Compatible ICEMAN VEST Pro X Thin ICEMAN Used last summer. Approximately 10-20 times. I am listing it because my work environment changed due to a job change, and I didn't use it this year. The items for sale are: - Water-cooling vest - Battery - ICEMAN charge bottle There is some fraying on part of the vest, but Pump operation -> Cold water circulates through the hose -> The body cools down, so there is no problem in use. If you put two frozen plastic bottles in the bottle, they will melt during use and you can drink them, which is a win-win situation. I don't think I used the charge bottle very often. Pump operation confirmed. Thank you.
