It is more of a rain jacket. Not going to keep you warm in the cold winter of TO.
It is meant to be worn with layers underneath in the fall, but not super cold snow weather.
Are your Hackett sport coats full canvas construction? Specifically this one: http://www.malfordoflondon.com/en/jackets/1779-gieves-hawkes-white-linen-patch-pocket-jacket-rrp-600-gbp.html
I bought a Bamford & Sons Loro Piana cashmere coat. Very fine quality. I would say it is equivalent to Brunello. Only problem, it is tagged 42 but is more like 39. Runs very small and tight.
Great quality and if they are no longer...
