Hey Brian, same problem here...
I used to go well into January before putting on a coat to perform my (10-15 minutes at a time) outdoor work. Now I'm bundling up and have been since October.
I'm sure as Cookslav mentioned you will become acclimated to it... as we all do from late fall to early winter. Us newly 'skinny' guys (lol) are feeling the early chill twice as bad having to adjust to the weight loss.
Instead of suffering, I looked hard into dressing for the weather. Most of my solutions came from Mark's Work Warehouse "Windriver" selection. The "NO COTTON" approach really paid off at Quinte!
Windriver thermal underpants: $22
Windriver thermal undershirt: $22
Windriver thermal socks (3 pack): $19
Windriver insulated rain pants (30% off): $69
Viking uninsulated rain coat:$69
Kmart hoody: $15
Sorel Glaciers: $129
I was toasty warm and dry for the 4 miserable days we spent at the BOQ and never broke a sweat in temps ranging from -2ish to +10ish C. I also purchased the Windriver insulated rain coat (30% off): $169 but I have to wait for Christmas to get it! Staying warm doesn't come cheap and it sure helped getting advice from others that spend a lot of time in cold climates. (Thanks guys for your PM's)
