"The Patagonia Better Sweater Crewneck is the pull-on layer that earns daily rotation: midweight fleece that handles a cool morning hike or an afternoon errand run without needing anything more. The face fabric and trim are 100% recycled polyester, and the pocket flap uses NetPlus recycled nylon, materials that carry the warmth without the weight of a heavier mid-layer. What Our Gearhead® Experts Are Saying:""I grab this on chilly mornings when I want warmth without fussing with a zipper. The crewneck sits clean under a shell and stays put when I'm moving."""
