Did 160 miles today in 25-30 degree temp.
I purchased a pair of leather coveralls (heavy grade) from stone lake leather works which work fabulous and a pair of Gerbing heated gloves which saves my life. Nothing worse than cold hands, that's all I think about once they're cold. I also got an Under Armor ski mask that really keeps my face comfy. Underneath I had on a pair of long johns and 2 thermal shirts under the leather jacket.
Out of the 160 miles, I did about 120 of the miles on the 4 lane to see how it all handles at 70-80 mph and I got to say I stayed pretty comfortable. I'm good to go. H
