The Helly Hansen Daybreaker women's polar fleece jacket is a must-have for all the outdoor enthusiasts. Made of Polartec recycled polyester and thanks to its versatility, this garment will keep you warm during all seasons, whether on cooler summer evenings at the campsite or under your winter jacket to face cold weather. 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.
