Merino wool and silk leggings give maximum breathability while comfortably insulating against temperature extremes. Wool prevents bacteria from settling, which greatly reduces the buildup of odour caused by sweat. The added elastane reinforces the natural elasticity of the wool fibres and guarantees that they will retain their shape in movement. They have an elastic waistband with a drawcord and back key pocket.
