Tilden S.wrote a review of Marmot Midweight Crew - Men's on April 17, 2010
I wore this for nearly three weeks straight while traveling through Siberia this winter and it totally exceeded my expectations. I had one extra set of thermals that supposedly had silver in it to cut down on odor, but it always began to smell after 24 hours and weighed twice as much as this shirt. I wore the marmot thermals practically the entire time and went up to a week without washing it with absolutely NO stench. Probably could have gone longer but that just seemed gross.
Next time I travel internationally for an extended period of time I'm just packing a couple changes of this shirt in a backpack. The odor control is amazing and it's super comfortable.
