The Mens 200 Zone Leggings from Icebreaker are lightweight, all-season baselayer bottoms with a gusseted design and a touch of stretch. The updated 200 Zone Leggings offer breathable insulation and unrestricted range of motion on any day of the year. The Zone features our BodyfitZONE construction, which combines lightweight, odor-resistant stretch merino wool with strategically placed merino mesh panels to help regulate temperature during stop-and-go days of skiing, climbing and cold-weather hiking. Flatlock stitching keeps these bottoms from chafing during day after day of dynamic motion.
