The hot weather continues. This is a full set of water-cooled clothing that can be used on-site. You'll likely need to buy additional items if any of these are missing. I think you'll be fine with just this set. ICEMAN PRO X SET Water-cooled vest x1 Battery x1 (5200mAh) ICEMAN Charge Bottle 5.0 x1 WATER MAGNUM x1 Charge Bottle 5.0 ICB-CB5-2 x2 Charge Bottle 5.0 ICM-CB5-T2 x2 ICEMAN Energy Charge (Blue) x1 I used the WATER MAGNUM once after setting it up. The tube has been cut and is ready for connection. I prepared multiple bottles to use on-site, making it a full set. The neck option is discontinued, so I think it's very rare. Cleaned. There are stickers on the Energy Charge, but please consider them as a bonus. Some parts may be peeled off. Yamasen Seikosho Y's GOD
