I just use some insulated mechanics gloves I got at Mark's Work Warehouse for $30CAD. The work great for all my riding. Only time they are a bit cold is when running at high speeds with a string wind, and also without a windshield or handguards. I installed Powermadd handguards and now don't have a problem.
