I use a Warm & Safe 12V heated shirt and, I have combined it with their heated leggings, socks, and glove liners once. After using it like that the one time, I have only dived with the heated shirt since. I just wanted to see what it would be like with everything on.
Warm & Safe Heated Clothing the Warmest Clothing in the Universe
I have been using their heated gear for motorcycle riding for over 10 years. It is really good stuff. I think the 12v heated shirt is better than the Light Monkey (at least, on paper - I haven't tried the LM). It's 7 heating panels, instead of the LM's 2 and puts out something like 42W (about the same as the LM). And the shirt is about half the price of the LM.
Their gear is all designed to plug together, if you want to add the leggings, socks, and/or glove liners.
