The Helly Hansen Varde 2.0 women's half-zip sweater is a must-have for your outdoor activities in the countryside or in the city. Wear it all year round for comfort and warmth. Eco-friendly, this insulating layer contains materials that meet the Bluesign® sustainable production criteria. This garment can be worn as a mid layer in a layering system providing comfort and warmth enabling you to regulate your body temperature by wicking moisture away during your outdoor activities. 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.
