The good reviews of trousers gave me the rash to spend 25 euros for a pair of underpants - and I can confirm the positive experience in terms of quality, seams and thermal properties after first experience. However, should such an expensive underpants then also fit perfectly - but the size designations M, L, XL, etc. are very open to interpretation. "Dear size up" was in some reviews - that has not really helped. So here's my size Experience: At 177cm / 74 kg I broadcast on the underpants Size 6 (sometimes 5), in the pants size usually fits 48 (sometimes 50; in US-masses: 32) and got me to try out the thermal underpants in sizes M, L and XL ordered. I fit the "L" perfect - is tight, but not too tight.
