The Womens 150 Zone Legless from Icebreaker are lightweight baselayer bottoms with a gusseted design and capri-length cut. The 150 Zone eliminate bunching while wearing ski boots or other high-cuff winter footwear. These leggings feature our BodyfitZONE construction, which combines lightweight stretch merino wool with strategically placed merino mesh panels to help regulate temperature during stop-and-go days of hiking, running, skiing or climbing. Our corespun fibers use nylon threads wrapped in soft merino wool and blended with Lycra for the ultimate combination of durability, stretch and next-to-skin softness. Flatlock stitching keeps these bottoms from chafing during day after day of dynamic motion.
