"Medium was too small the item was returned."
I am 160lbs. and 6'3". The pants were too small so I returned them as I was leaving for South Asia before I could receive a replacement. The Ibex Men's Woolies 150 zip up top that I ordered is working great.
i'm wearing these long underwear bottoms everyday. I have them under a pair of jeans at the moment in fact. They are light enough that I barely know they are there-- but yet add significant warmth. They seem to handle smells and moisture as well as all the other Ibex merino I own - haven't needed to wash them yet! Solidly built long-johns-- I definitely recommend them!
