great temp regulation and build quality, could use another color besides grey.............................................................

My new favorite layer for skiing. I have the reactiv base layer that on super cold days I will layer under this full zip. If it gets hot, I take it off and stuff it in my pack.

I was looking to replace my Patagonia R1, and this fleece beats it by a long shot. The fit is flattering and designed for women—not straight or clingy—and the temperature regulation is excellent. It’s thin but warm, perfect for layering under a puffy, and stylish enough to wear on its own. Great color options too (Graphite is a winner). Absolu...

As advertised, this is a great piece to have in your closet for lightweight warmth and breathability. It wicks sweat like a champ, is comfortable for outdoor activities, and can be layered beneath a jacket on colder days. I haven't tried it in the backcountry yet, but plan to this winter and can already tell it will be a new favorite. It's bee...
