Designed for snow sports and intense winter days, these Icebreaker leggings are part of a line of technical sportswear made from 100% merino wool. Its MerinoFine™ technology, featuring 15.5-micron fibers, ensures softness against the skin, natural temperature regulation, and long-lasting odor control. The high waist, mobility gusset, and flatlock seams provide support tailored for prolonged exertion in extreme cold.
Designed for women who participate in snow sports in extremely cold weather, these thermal mid-layer leggings feature exceptional merino wool to combine intense warmth with softness against the skin. MerinoFine™ technology, which uses 15.5-micron fibers, makes this model one of the thinnest and softest mid-layers in its weight class. Its heavyweight construction, corresponding to the 300 warmth system, meets the demands of the harshest winter days.
Icebreaker crafts these leggings from 100% merino wool—excluding the elastic—a naturally renewable fiber that is harvested annually and serves as an alternative to petrochemical-based synthetic materials. Thanks to the inherent properties of this wool, the garment naturally regulates body temperature and minimizes odor buildup, even during prolonged exertion. The fabric’s high weight ensures substantial thermal insulation without the need for additional chemical treatments.
The high waist provides extensive coverage of the torso, which is particularly appreciated when the leggings are worn under an outer layer while skiing or participating in other snow sports. The integrated gusset promotes a full range of motion in high-stress areas, while flatlock seams eliminate friction points that could irritate the skin during long outings. The 70.8 cm inseam (size M) provides the ideal length for wearing as a base or mid-layer under ski pants.
The fine 15.5-micron fibers require careful care to preserve the fabric’s quality over time. Machine washing on a cold, delicate cycle—without fabric softener or tumble drying—is recommended. Laying flat to dry in the shade and ironing on a cool setting round out these care instructions, which help preserve the thermal properties and softness of MerinoFine™ over the long term.
The Icebreaker W 300 MerinoFine Polar Leggings are women’s thermal leggings made from ultra-fine merino wool, designed for harsh winter conditions and suitable for mountain snow sports.
