Crikey! 4 years ago When it was freezing or below, my hands were still really cold after about 15 mins so I looked for something else. I now use the below as liners with Sealskinz Winter Finger Mitts. The mitts are a bit cumbersome but they do keep my hands warm far better than gloves.

For longer rides I also love wearing mitts, nothing worse than frozen fingers and a long way home ahead..
