User Review: Marmot Men's Midweight Zip LS
Price Paid: $25
I love this shirt. It is warm and light. In my opinion it is not only a great base layer but also good as a long sleeve shirt worn over an Under Armour tshirt. Breathable and I like the Cocona technology.
I got lucky and got mine 40% off at Sun and Ski due to seasonal clearance. It is a little bit less smooth of a material than others but still comfortable. Buy one.
