Not just good. It's grid.
Grid fleece is both familiar and like none you've encountered. Look carefully at the grid design since it serves a few purposes. One, it increases airflow and breathability, so you never feel stuffy. Two, it's even warmer than a standard fleece when layered. Three, those things combined make it adept at indoor-to-outdoor transitions (and vice versa). And did we mention it just looks cool, too, in this zip-front jacket ... with perfect pockets?
