Lululemon down front crewneck sweater

When I felt this sweater, I had to have it. The front is like a water resistant down puff layer to keep you warm from front facing breeze while the rest of the fabric is this buttery soft incredible fabric that’s breathable and stretchy. I have no idea what it’s called but it’s so soft. I’m still debating selling this as it’s so comfortable but I need to thin my closet so I’m going to part with it. Light cuffing on the hem and sleeves; navy blue.
