Designed for life in motion, the Mountain Hardwear Men's Cragger 12 Zip Shirt keeps you comfortably warm when you're climbing at the crag, hiking along your favorite alpine trail, or simply cruising around town in cooler weather. Its High Rock Terry fabric is predominately cotton, with added polyester for quick drying performance. The 12 zip neck opening facilitates better ventilation when you're working up a sweat, while Wick. Q moisture wicking pulls sweat off your skin to prevent the cold, clammy feel after exercising. Additionally, there's a zippered chest pocket for convenient storage of small snacks and accessories.
