This is the perfect down pullover!! It is super lightweight, but still very warm and windproof. It is also very water resistant. I got splashed by a wave on a rough ferry ride and the baja dried off in a few minutes, with no loss of warmth. Love the little details like the side zip, which allows you to pull it on more easily, and the inside zipper pocket. I initially ordered an XS based on the size chart (my normal 27 waist), but decided to size up to a S so I would have room for layers underneath.
