2XU HEAT SS RUN TEE
For such a seemingly simple item, there are many boxes to be ticked to make a truly great running tee. This does the basics – anti-odour, fast-wicking and quick- drying for zero ‘body cling’, and UV protection – with aplomb, but it also features ceramic-infused yarn, which creates a thermal effect to retain body heat and keep you toasty on nippy days. Guaranteed to be a staple for many years. £45, 2xu.com
