I actually don't have the Gerbing gloves. I couldn't justify the cost. Although, probably 3/4 of the riders in my chapter have them. I did get a pair of the Gerbing liners but only wore them for about a half hour. They're the older style, 5 yrs old, with the bulkier wires that made them too uncomfortable to wear. I got some simple liners, Patagonia brand, from a ski shop. Very thin, no effect on glove fit but a huge increase in comfort.
I tried the Gerbing socks at the dealer and rejected those before I put the boots on. My closest Gerbing dealer is about 60 miles away thru lots of Dallas traffic so I haven't been back there for a while. But the Gerbing website says they have a new type of heating element that eliminates the heavier wires. Should be much more comfortable. If I'm near there, I'll have to go back and look at the glove liners and socks, again.
