I read up on the power drain
because that is a concern of mine too, and it is certainly not non-existent. Using Gerbing
as an example, they say that the socks use about 1.8 - 2.1 amps (at 12vdc'ish), pants 3.6 - 4 amps, and a vest liner uses 4.5 - 4.6. That's about 11 amps for the whole outfit, or 130 watts continuous. That's enough to be concerned about if all you had were solar panels, though it probably wouldn't be a concern at all with a wind generator in winter.
I ordered something earlier today to try it out and see how well they work.
