“I received this as a gift and thought it might be too thin to be of much use. However, I gave it a try by wearing it on top of a wicking tee and a wool base layer on a sub-40 degree, windy day hike. It wound up being all I needed as I adjusted the zipper opening to match the protection I needed from the wind. I left my puffy jacket in the backpack.”
“It's been a great jacket to layer on for colder winter runs, I tend to overheat on runs even in the cold so this kept my initial warmth when I first start my run but also was breathable enough for when the sweat comes in strong.”
