The outer fabric of the Routa Winter pants is made from windproof Stormwall fabric, a familiar choice from many popular Halti products. Pair them with suitable base and mid-layers depending on the weather and activity. These pants are versatile, functioning as general-purpose pants for leisurely walks, winter hiking, or keeping warm at camp, and they can also serve as snug skiing pants on colder days. - Regular fit - Windproof and somewhat water-repellent - Microtherm Thermofill 80g/m² insulation mimics the structure of down: instead of a uniform wadding layer, the fiber is loose and super lofty for its weight - Belt loops *Routa* is the Finnish term for permafrost or frost, a situation where water in the soil has frozen.
