i have the DC volt jacket and i rarely wear it because its so damn warm. i ride so cal so i really dont need more than my burton dryride jacket and a t-shirt or something underneath most of the time.
this jacket is the warmest ive seen. its pretty thick but very light, and it has a ski-mask sewn on near the hood and liners for your hands. i dont know if they still sell it.
