Aircore® by Polartec® is created exclusively for Lands’ End® using unique hollow-core channeled yarns in an ingenious knit to trap more air, producing more warmth and softness. This innovative fabric is also breathable and incredibly durable. Our Lighthouse Half-Zip brings you all of these benefits in an easy layering silhouette that has a lighthouse logo stitched on the sleeve in a subtle nod to our sailing heritage. The Half-Zip resists pills to stay smooth and look new longer, is antistatic to prevent cling, and is brushed and napped for an even softer soft. Fits comfortably under heavier jackets or over lighter tees — an invaluable investment for the season. 100% polyester. Machine wash. Imported.
