I just watched Mr Squeegee's video. Pretty good stuff on staying warm in the winter.
I wanted to show you what gloves (mitts actually) I use to stay warm in the winter. These mitts are much warmer than the typical mitts window cleaners use, they are cheap too. In Canada I can get these mitts for just $17 + TAX at LeBaron at Dundas and Hurontario in Mississauga.
99% of the time your hands will be warm. So invest in some nice Ice Fishing Mitts, these are what I use.
I would recommend using mitts. I know it's personal preference but mitts keep your fingers together, thus giving your hands more heat.
Try it out, if it doesn't work for you - I doubt it, it's just $20 out of your pocket.
But I have used these mitts for 7 winters. Cold Canadian Winters, and I have been very happy.
Another thing, I never feel a cold aluminum pole through the mitts. Never!
