I have made in China motor-cycle cold gloves from autojumble, u can buy new in store, 15 - 20 euro, I think.

They are warm but not good for bicycle. Tint from leather makes hands blue.

But!

They have in little pockets thin nylon mittens for putting on under rain. I put just the mittens over Fila ski gloves, and ecco! Like booties for hands! Warm to below zero, fingers can shift and brake.
