This is Norrona's Roldal Warm1 Shirt. It's a nice button/snap-down that's designed to be used as a technical shirt. Norrona's description of the shirt is: Clean, soft and minimalistic women's fleece shirt, ideal for active freeriding, made out of gridded Polartec® lightweight micro fleece.
It's very soft, comfy, and warm. The only reason I'm selling it that I don't have much in the way of curves (5'8"/125 lbs) and I think this shirt is really designed to fit someone curvy. It doesn't look that good on me (it flares out a bit at the waist/hips), so I don't wear it much. Norrona makes high-quality stuff and it deserves a better home!
It has a snap chest pocket and snaps down the front. No notable wear or flaws.
The color is called "cool black" - it's sort of a charcoal navy. Not black but not really navy either.
