Shoppers are flocking to Marks and Spencer (M&S) to buy a £12.50 thermal top that keeps them so warm, it's helping to reduce heating bills. The M&S insulated top has been created with Heatgen™ technology, which helps to lock in warmth.
M&S' Heatgen™ Thermal Long Sleeve Tops come in packs of two, and cost £25. That works out at £12.50 per top - or you can buy them individually for £16.
The M&S heated tops are available in various different colours and designs. There's plenty of plain colours like black and grey for basic use, or you could opt for the sparkly thermal top if you're looking for something warm and festive under your Christmas jumper.
