Castore Performance Active Technical ¼ Zip

£105, castore.com

You’re not going to be missed in this ‘fiesta’-coloured ¼ zip from premium activewear brand Castore (also available in four other colourways). Ventilation holes in the back – ‘laser cut’, apparently – are designed to increase breathability, though in truth this is one for dark, cold mornings, rather than sweaty summer running.
