The Ocular pants use two strengths of Thermic fleece: the main fabric is 265g/m² in material weight and offers ample stretch and insulation, while a lighter 160g/m² fleece is used in spots where top notch breathability is more important than insulation. Despite having been designed for ski touring use, mid layer pants like this are useful in many other uses as well. - Slim fit, best for slender figures - The stretch fleece material has a smooth outer surface and a brushed inner surface - Stretch waist with adjustment elastic cord
