The best fabric for keeping warm and cosy is fleece. Fleece is named after the organic material from sheep but the Regatta Women's Micro Full Zip Fleece is made of man-made polyester-based microfleece. The Layer Lite Fabric Technology has three benefits: First, it is fleece, which means it is able to hold air pockets in between the fibers which contribute greatly in keeping you warm and snug. Second, it is moisture wicking fleece. This means that it moves moisture from your body to the fabric surface to evaporate, leaving you nice and dry. Third, it is very light. With fabric weight of 210gsm this fleece jacket's fabric weight is comparable to a high-end polo shirt. If you are looking for smart and stylish jacket that combines the warmth of fleece without the heft, look no further than the Regatta Women's Micro Full Zip Fleece.
