Self-Warming Jackets
jeffy124 writes: "Those of you in the frigid north who find their coats unfulfilling of their duties may be interested in a self-warming jacket. By using steel microfibres woven into the fabric plus a lithium battery, heat is actually generated to as much as 114 degrees fahrenheit. The jackets, sadly, come with a nasty price -- US$500. Among those interested in purchasing are skiers (including some Olympians), and the Military."
You don't need electric heating to be warm on a bike. Just get a decent quality bike jacket that was made this decade.
I have a decent motorcycle riding suit and probably go out at temperatures that would freeze your eurobutt. I can dress for riding down the highway or I can dress for around-town. But if you mix the two, you are either too hot or too cold.
Besides, I don't like having to deal with a full riding suit when I just want to take a run to the store, go to a restaurant, etc.
By the way, when you say "90 on the motorway", do you mean 90kph or 90mph? If it's kph, I have a scooter that's almost that fast and if I rode 90kph (56mph) on the highways around here, I'd be squashed within a week.
