The Progress MB SDND women’s functional leggings are made from a mix of two natural fibres with functional properties. The outer layer is made of fine micron Merino wool, the inner layer is made of viscose fibres with bamboo content. The material is soft and pleasant to the touch and its properties surpass traditional synthetic materials. Merino and bamboo fibres promote better thermal regulation by providing cooling and warming effect depending on your body’s current temperature. Merino also prevents bad odours and keeps you warm even when wet. Combination bamboo -merino is perfect for all types of outdoor activities. Therefore, base layer made of this material provides ideal protection against extreme weather during all outdoor activities from hiking to climbing.
