SmartWool Midweight Zip T
Price Paid: $50
Fact: this top is my favorite piece of clothing. If you look at any of my other reviews you will see that I spend most of my time in that fine, kind, merino. That being said, this top (of which I own 2), is my most used piece of clothing. It doesn't seem to matter if I am hiking with weight in the 60's or stopping for a break in the low 40's. I spend the majority of my clothed life with this shirt on.
The zipper is a huge plus in terms of thermal regulation over the crew. It allows you to open and vent to cool off or zip up and seal off your neck to heat up. It will not smell after days on the trail and will not melt if an ember finds its way to your body. I love this shirt
