First impression
The button shirt and long john pants feel as expected. The wool is nice and soft, the material light, the color unobtrusive. The pants have a nice, snug waistband that doesn't slip. As a small special feature, the shirt has a buttoned neckline. The workmanship is impeccable.
Tester and test conditions
I am 183 cm tall, weigh around 75 kg and wear both items in size L, which fits well. The shirt is not too loose, but is also not skin-tight, as some athletes prefer with functional underwear. I would probably have to wear a size M for that, but L is fine for me. The set has been tested on most of my skiing days since just before Christmas and has been in use on an estimated 20 days and therefore in the washing machine a few times.
