A popular, versatile garment, the Ibex Women's Shak Full Zip Top is ideal as a midlayer, soft and itch-free for next-to-skin expedition weight insulation, or tough enough to serve as an outerlayer in moderate conditions. Made of 100% dense knit merino wool, the Shak Full Zip Top is durable, breathable, and offers natural stretch, a wonderful combination for such a versatile piece.
