Riding in cold weather never used to be a problem. Now I have a much longer commute. With all my leathers, boots, neck and head gear, I'm pretty nice and warm. Except for my fingers. The first ten miles are ok. After that my fingers start to hurt then eventually go numb. When I get off the highway it is difficult to operate the clutch & brake. The snowmobile gloves I wore with my last sport bike don't work. Surgical rubber gloves under my lined deerskins seems to be my best option so far.
Anyone ever seen a streetbike with those offroad brushguards in front of the grips?
Do I just have poor circulation or do others battle this problem?

Got Milk?

Ages and ages ago I was hunting with my uncle near 100 mile house, BC.  Ran out of milk, had to go pick some up.  Hopped on the old DT175, dressed in thermal underwear, wool pants, wool shirt, goose down vest, wool jacket, 3/4 helmet with bubble, and a pair of down mittens similar to:

About 10 miles through the falling snow.   My hands stayed toasty warm.  The rest of me suffered.  If you do one-finger braking you can find hunting mittens that have a hole for the trigger finger.

Aerostich has several glove liners available, from synthetics, to silk to kevlar.  At $12 a pair for 100% kevlar,I picked up a pair of the kevlar liners because they add some warmth and a little extra abrasion resistance.  So far as thin liners go, I think the silk would probably be one of the best for warmth though. Silk is actually pretty durable too... and not bad at $9 a pair.  I think the least expensive liners were about $6 a pair and they go from there.

MY big lovable but sometimes dumb husband rides his Volusia in weather as cold as 25 degrees...*sheesh*...and he swears by some gloves he bought at a Wal-Mart. Big, thick, and waterproof...for about 12 bucks. He tells me at temps below 25 after 30 miles his fingers begin to feel cold....
