After trying different equipment to be comfortable in extended hwy riding in temps in the low 30s, I could keep everything decent except for my finger tips. Tried better winter gloves and glove liners that helped but it still got painful on the finger tips.
So a friend told me to try good mittens. I thought they would be hard to ride with so never considered them. I bought some winter, water-proof mittens and did a test today.
When I left the house about 8:30 am the temp was 35 degrees with a constant light rain. I put on my thick gloves with silk liners and thicker liners over them. Within 10 minutes my finger tips were uncomfortable already and I was still in the neighborhood area. The hand control feeling was not good but manageable.
I then put on the mittens over the same double liners. They were warmer after riding for about 10 minutes but I got cramps in the webs of my hands between the thumbs and pointing finger. So I took off the silk liners to allow more room. Much better then and very good hand control feeling.
After about 15 minutes of hwy riding my finger tips started to get chilled, so I just tried letting my finger tips not grip and point more straight so just my palms were griping. This allowed more of an air gap all around the finger tips. WALLAH!!! My finger tips got warm again except for my thumb tips. So I extended my fingers over my thumbs and tucked my thumbs under the finger air flow so my thumb tips were shielded by the mitts. I rode for about an hour and a half like that on the hwy and ALL was comfortable as long as I didn't grip with my finger tips. The gloves gave me no relief no matter what I tried.
So if you were able to stay awake through this boring post of mine, it is true, mittens ARE better than gloves, especially when the correct grip technique is found.
Just got home and the digital temp reads 37 degrees so the weather stayed consistent.
