I've become disenchanted with liners.
I have Thinsulate glove liners that I was inserting into lobster style gloves on cold days. I was mystified that my hands were still cold.
For the last feww days, I've ridden without the liners and have been warmer.
I think the liners defeated the purpose of the lobsters, which is to have the fingers warm each other.
I tried the half-finger gloves with foldover mitten flaps, too -- with and without liners. At temperatures around freezing, they seemed better without.
