seriously folks, if you're still riding, get one. They're a godsend. I just bought mine on Saturday, and it's pure bliss. Trevor at Burnaby Kawaskai sold one to me for a little over $100.
Also, my fingers didn't get nearly as cold because you keep pumping warm blood out of your body's core which helps your extremities.
After experiencing this and re-evaluating my wardrobe. I figure that this is what you need for cold weather:
1. at least 1 pair of longjohns underneather your pants, (maybe 2), (I wear a pair of track pants underneath)
2. a heated vest
3. glove liners used with non-perforated gloves, (no race replica gloves, most have small holes in them).
4. a balaclava or ski mask underneath your helmet
5. boots with high tops
