You'll wear the Icebreaker Women's Zone Legless Tights more often than just for winter skiing. Their merino wool provides lightweight thermal regulation that feels great when you're alpine trekking in summer and climbing in the shoulder seasons. Merino wool also naturally resists odor and provides a long-lasting smooth feel. Icebreaker added some Lycra to ensure proper stretch and freedom of movement. BodyfitZone technology places merino-made mesh panels for ventilation, and the 3/4-length accommodates ski and mountaineering boots more comfortably.
