You'd be hard-pressed to find a cozier combination than fleece and merino wool. The Ortovox Women's Fleece Plus Knit Hooded Jacket blends merino with fleece to amplify temperature regulation, moisture management, and breathability. The result is a full-zip that you can feel comfy in during cold ski tours and warm cabins alike; merino wool also holds natural anti-odor properties so you can do both if you really want  to.
