This is a full-circulation water-cooling vest from BRAlN. I purchased it new and used it once. It wasn't suitable for my intended use. Everything that came with the purchase is included, but please note that this product does not come with ice packs. Also, due to the structure, it is difficult to completely drain the circulating water, so please be aware that some residue may remain. #Iceman #YAMASHIN SEIKO #Peltier Cooling
