The Cold hands due to cold/wind question had a number of good recommendations, including using gloves with Windstopper branded material. My ski gloves are worn out so I purchased this silk weight Windstopper pair of gloves (WARMER - not WARMEST or WARM) last week to see if it could measure up to ski gloves.

They did not even come close. Commuting between 17-25 MPH on an electric bike in pedal assist mode (high cadence, low effort) at 50 degrees or so for 20 minutes, my hands are cold, and do feel the wind a little. My 10 year old thick ski gloves are much warmer. The upside of this pair of Windstopper gloves is that my fingers are fully mobile, as compared with my thick ski gloves which reduced finger dexterity to the point where it reduced reaction time for shifting and ringing the bell.
This morning I tried using regular bike gloves worn under the Windstoppers, and that at least kept my palms warm, but fingers were still cold.
What is the best way to use Windstopper-based gloves. Do they require liners to be effective?. If so, which brands/models are appropriate for which temperatures?
