I ordered these pants in medium size and I am a bit disappointed with the fitting. The legs are very tight and the waist slightly large. The end result is that the crotch level is about 3-5" below my actual crotch... Makes me feel like I am not wearing it properly and that I may lose my pants if I was going hiking with them.
Warmth wise, they are doing an excellent work.
The fitting may be getting better with the use but so far, not so good...
