Warm, Versatile, Lightweight
At first when I received this this shirt I questioned its durability but it has stood up to the test of time. When working out on the trail when it was nearly always raining this was my go to layer to keep me warm even when I was getting dumped on. After putting it on I would instantly feel the difference it made. The zipper is key to giving some ventilation when the sun (rarely) peaked out of the clouds.
The shirt was very comfortable as a base layer and stay far less stinky than other shirts even after being warn on a trail worker who hasn't showered in a week!
