Point taken, but I didn’t forget about it. I go hiking and tenting on the ice on Lake Diefenbaker, so I know all about it. I just didn’t know how to bring it in without lending yet more credence to all the myths and misconceptions.

There are a lot of differences between actual -25C with no wind and windchill of -25C. For example at -25 with no wind, my wool parka with a fairly open knit is perfect on its own for a wide range of activities. But with a windchill of -25, I’m better off with my fleece bunny hug under a windbreaker, then layering up with a tightly knit wool sweater when I’m inactive.

When I still biked, -15 with no wind quickly turned into -25 windchill, but if the windchill was already -25, hopping on the bike didn’t make a huge difference, so I dressed about the same in both cases.
