Marmot's Thermo 1/2 Zip Top is made of polartec Power Dry fabric - which we are very familiar with - its a supremely comfortable fabric worn next to the skin or over a light baselayer and wicks sweat away from your body very efficiently.
Using Power Dry in a 1/2 Zip format means you can vent quite easily as well as relying on the fabric to keep you comfortable. Power Dry works best next to skin or over a thin baselayer, if you wear it over anything thicker you will not get the benefits. This type of garment makes a nice top for 3 season hiking in all but the hottest conditions.
