I feel comfortable in the long underpants. Tightening is something ansträngend because it is a bit tight and I probably have slightly wider feet than the model pictured. Otherwise underpants sitting well. Why are today called 'thermal underpants' almost all briefs, I am not sure. However, the winters are milder because sufficient long underwear. The term 'thermal underpants' I got to know very thick underpants that keep very warm even at high minus degrees and I could not bear in heated rooms, since I then permanently sweating. These pants I could even at + 18 degrees in the room still wear without sweating.
