John Lewis Heat Generating Long Sleeve Roll Neck Thermal Top, Ivory

As the temperatures drop thermals become essential and this long sleeve roll neck top is designed to generate and then trap heat.

Depending on quite how cold it's become you may want to wear it on its own so we've given you some bright and bold colours to choose from. But it works equally well as a base layer as it's designed to fit snuggly against your skin and hits just below your hips for tucking into your skirt or trousers.
