This is the "ChillerX" released in August. I'm including the Elecom "EC-C17LBK" battery, so you can use it immediately upon arrival. Both the vest and the battery are in excellent condition, having been used only a few times. The cooling is more moderate than the IceMan, but I've confirmed it works with the motorcycle USB power supply "Kaedear: KDR-B13". So, if you connect it to that USB power supply, you should be able to cool yourself continuously during touring without worrying about the remaining battery charge. Due to the nature of the product, it's impossible to completely drain the water inside. Please read the instructions and replace the water before use. Due to the nature of used goods, no claims or returns are accepted except for initial defects.
