I did a few Wintex's in Valcartier mid-winter in the old olive green uniforms. It was light recce force vs light recce force stuff. We hit -35C (which is where the scales match one another, for our American friends) and lower at night. We slept in survival caches we built for ourselves in the deep snow (usually under a canopy of evergreen). All the gear -mukluks, Extreme Cold Arctic Combat pants and jacket, mitts, tuques and double layered sleeping bag - was made in Canada and not only did we not get cold, but we were nice and toasty in the bags and, after only half a kilometer walking or snowshoeing, we had to strip the jacket open because we were too warm.
How can we, in Canada, forget how to produce gear like that?
