The Icebreaker Fastray thermal leggings are a warm and functional merino wool base layer for the coldest months of the year. The trousers are ideal for trekking expeditions, skiing, snowshoeing, and other cold weather activities.Merino wool fibre is naturally renewable, recyclable and biodegradable under certain conditions. Thanks to its natural bacteriostatic properties, the leggings are odour-resistant, even for several days. This is extremely comfortable during trips or long treks. Thanks to the gusset in the crotch and the flat seams, the leggings provide the wearer with full mobility, comfort and protection against abrasions. The medium weight of the wool used (260 g/m²) provides adequate insulation and optimal breathability in winter. The dense knit ensures an even distribution that does not lead to over-stretching and over-clearance. There is also a pocket on the right leg to accommodate a phone. The high rise, close-fitting cut and elasticated leg and waistband trims make the Icebreaker Fastray fit like a second skin. Women's thermoactive leggings Icebreaker Fastray 0a56ew-ib001
