Cold Weather Clothing

One Rider's List of Cold Weather Clothing - by Degree!
Whether or not you buy into riding at 130 F or -45 F, this is a good list to examine for your own less extreme riding. This rider is obviously less sensitive to cold weather than the majority of us - you may want to add a little more protection at each temperature level than he describes here. Thanks to slvoid at Bike Forums (Winter Riding) for sharing his insights and his sense of humor.

But I usually push pretty hard so I warm up. If I'm going a bit slower, bump everything up by 1 layer. Also, this is in the city, where I'll be drafting heat off cars and doing a lot of stop and go (which means the wind isn't continuously sucking heat off my body). It'll usually be a few degrees colder on the open road vs. the city so I dress appropriately.
