We look like "Rangers Family" in the Highlands in winter. They're definitely too hot for the summer, but we've been using them for the last few weeks up in the snow without any baselayer without feeling too cold, although I would normally use a baselayer if it looks like being particularly cold or windy. The Tactel inserts shed snow, so that's always handy. I'm happy enough with them not to bother thinking about replacing them, so that's usually a sign that something is doing a good job.
