Zueike Clothing from MB

Not sure if this counts as the material is sourced from overseas but it's Winnipeg owned and operated. Their Luxe line is the most comfortable clothing I own. They also take part in social and local initiatives.

I have broad shoulders and I find their Luxe clothing just fits better than the cheap off the rack stuff. On the zip and the long-sleeve I did have to size up from an xl to xxl
