维基的解释，比干衣复杂多了
Hot water suits
Hot water suits are used in cold water commercial surface supplied diving.[9] An insulated pipe in the umbilical line, which links the diver to the surface support, carries the hot water from a heater on the surface down to the suit. The diver controls the flow rate of the water from a valve near his waist, allowing him to vary the warmth of the suit in response to changes in environmental conditions and workload. Pipes inside the suit transport the water to the limbs, chest, and back. Special boots, gloves, and hood are worn. These suits are normally made of foamed neoprene and are similar to wetsuits in construction and appearance, but they do not fit as closely by design. The wrists and ankles of the suit are open, allowing water to flush out of the suit as it is replenished with fresh hot water from the surface.
Hot water suits are often employed for extremely deep dives when breathing mixes containing helium are used. Helium conducts heat much more efficiently than air, which means that the diver will lose large quantities of body heat through the lungs when breathing it. This fact compounds the risk of hypothermia already present in the cold temperatures found at these depths. Under these conditions a hot water suit is a matter of survival, not comfort. Just as an emergency backup source of breathing gas is required, a backup water heater is also an essential precaution whenever dive conditions warrant a hot water suit. If the heater fails and a backup unit cannot be immediately brought online, a diver in the coldest conditions can die within minutes; depending on decompression obligations, bringing the diver directly to the surface could prove equally deadly.
多冷啊，买个7-8mm的半干衣也不行么？
加热的多半不靠谱啊
pp上贴俩儿暖宝宝。。。。。。。。
没空气不能发热。。
考虑用其它的替代。。
反正一潜基本1小时不到，可以用一种掰片的替代。

哈哈，denovo的链接一的衣服用heated wetsuit这个名字只是个产品策划，链接二看起来很神奇，可以试试
mark 一下
听起来不太靠谱，发热容易，要发热均匀并控制温度很难。
干服么,多下水就会了
