This is the perfect layering piece. The merino blend material on the sleeves and back is stretchy and just warm enough for a light jacket on its own or on top of a baselayer/underneath a shell. I wear this running, skiing, hiking, and even when I'm just out shopping, etc. The quilted material on the front is windproof which makes it perfect for the aforementioned activities, and the breathable back saves me from getting too sweaty. I like the contrasting color of the pink zipper (I have the clearwater colored jacket—gorgeous color, by the way), but the material on the pocket is very see-through. The hand pockets are excellent. They're incredibly warm for when your fingers start to freeze, and are fairly roomy for a formfitting jacket. I recommend this for all activities and all seasons. Looks great on, too!
