A bit of windstop, no fleece or any other warmer, stretch very well, XL waist is 35~45cm, inseam 72cm, outer leg 102cm perfectly fine for my 175cm/78kg
The pants seems to be made from a good material and it fits perfect to me (I am 1,70 m and 75 kg). I am pleased and I will came with a additional feedback after I will wear the pants, to see how are doing in real life.
