Abstract: A personal watercraft garment heating system is disclosed that will provide warmth to a user of a personal watercraft in cold weather. The garment can be either a dry suit or a wet suit that has tubing incorporated in the lining of the garment. In one embodiment the heated fluid is diverted from the personal watercraft propulsion system and manually metered into the tubing incorporated in the lining of the garment to obtain a comfortable temperature. In another embodiment the heated fluid is diverted from the personal watercraft propulsion system and manually nixed with non-heated fluid to obtain a comfortable temperature. In both embodiments the heated fluid is transmitted through flexible tubing to the garment through flexible tubing in the garment and then dumped overboard. A quick disconnect in the flexible tubing to the garment is provided in case the user falls off the personal watercraft.
