Bikers, what's the best piece of winter gear you've ever found?

if you take a long scarf, fold it in half, and pull the two ends through the loop, and pull it tight around your neck, you can tuck it into your coat. Like this.

Under Armour will help a lot when worn under your normal gear. They have a hood thing that will help with that scarf issue as well.

I bought some Harley Davidson gauntlet gloves Not only are my hands toasty, but they prevent the cold air from traveling up my arms and around my back beneath my jacket. I love ‘em! They’re well worth the expense.
