OAKLEY FLIGHT JACKET

A major investment but it pays off. The incredibly light, practically bulletproof frame is shaped for a super-secure and comfortable fit, aided by nosepads and ear grips that handle perspiration with ease. The open-edge brow increases your upper field of view, and the Prizm lens technology, which quickly adapts to different light conditions, is absolutely superb for enhancing contrast and definition. This latest version also features an anti-fog gizmo: pulling down a toggle on the bridge allows in extra air to clear any heat build-up. £185, oakley.com
