I'm in the same situation as you, though I don't know how the weather is in Toronto.
Luxire has the following options:
Black (16 oz), Navy (14 oz), grey (12 oz) and camel wool (14 oz) at 249$. The brown twill (11 oz) and grey plaid wool at 16 oz are also at 249$.
New additions are the Dugdale Charcoal/navy at 25 oz but that brings the total up to 449$. I was originally thinking of getting the quite cheap one in navy at 249$, but I'm afraid 14 oz might get too cold in wintertime. Would you reach for the Luxire peacoat at 449$ with 25 oz dugdale wool?
Will be used for Norwegian autumn/winter - temperatures might drop down to about -10 to -15 degrees celsius.
The Schott peacoat at 32 oz ends up at about almost the same total, but then I think I'd rather get one from Luxire. (with shipping and taxes added to the total) The only one Sterlingwear offers at 32 oz has an unvented back, which imo isn't that great of a look.
The ones they offer at 24 oz aren't that heavy compared to the Luxire one and probably might cost the same as the one from Luxire. (after shipping/taxes)
Right now it's about 10C but it doesn't get to -10 until late December really. I can't wait close to $500 for a peacoat when there are so many on the market but that's just me.
I had a sterlingwear and that was plenty warm with just a sweater underneath so I"m assuming 12oz won't cut it.
