"What Our Gearhead® Experts Are Saying:""This windbreaker is a go-to shell when the forecast is uncertain. It packs down small, sheds light rain, and gives me sun protection without overheating. I’ve used it on exposed ridgelines and around camp—super versatile and easy to stash."" From unexpected gusts to midday sun, the Acker Rock™ Windbreaker is built for changing conditions in rugged places. Made from durable 100% nylon and finished with Omni-SHIELD™ advanced repellency and Omni-SHADE™ UPF 50 sun protection, it’s ready to block out wind, fend off drizzle, and keep UV rays at bay. Its relaxed fit layers easily over a tee or midlayer, while thoughtful features like a drawcord-adjustable hood and hem, zippered chest pocket, and kangaroo pouch boost both function and comfort. When the sun returns or the winds settle, this windbreaker packs down quickly, ready to disappear in your pack until you need it again."
