The Icebreaker 260 Vertex women's baselayer pants are made of soft merino wool for an incomparable comfort. This baselayer is the perfect foundation to keep you warm under your winter sports equipment, for your everyday cold-weather layering system. Made with warm, breathable fabric, it naturally resists odours all along the day. The slim fit and the gusseted construction provide unrestricted freedom of movement while the elastic waistband and the flatlock seams reduce chafing when you're on the move. A must have for all your outdoor winter activities, such as hiking or alpine skiing. This garment is part of a layering system that provides comfort and warmth for your outdoor activities. Easy to layer, this base layer enables you to regulate your body temperature by wicking moisture away. This onion layering system is made of three types of clothing. The first layer, worn next-to-skin will provide warmth and quickly move moisture away from your skin. Then, the second layer, is the insulation or fleece, that provides warmth while also dissipating heat during periods of high output. And finally, the third layer, the shell, which is the most weather-protective layer, worn on the outside of all other layers.
