I don't know what magic this fleece is made of but boy, does it keep me warm like nothing else! I am always cold and this top has me soo toasty even in a fairly chilly house. I'm so glad I purchased it as it has saved me through the winter. The design is beautiful and the fleece is super soft - gutted to find they'd all sold out literally a week after me collecting my order but, I'm not surprised! Don't normally shop at Next but would happily repurchase one of these if another range is brought out next Winter! A life saver during an energy crisis and looks so beautiful was happy to wear it out of the house despite it being labelled "lounge wear"
