I have the Gerbing thin jacket liner and LOVE it. I also have thier glove liners (same electronics as the full gloves, but in a soft cloth liner that fits under your gloves). Together they draw 99 watts on max but I usually set the digital heat-troller at 1/2 to 3/4 which pulses power to the Gerbing gear thus sparing the charging system somewhat.
I have the Gerbing pigtail (Type N coax power plug) direct to the battery and then use the heat-troller velcroed to my tank bag.
