Koo Supernova sunglasses

£169, velobrands.co.uk

Koo’s Supernova sunglasses weigh only 21g – about the same as a teaspoon – but they pack some impressive tech. The one-piece lens has no frame, so no blind spots. It is 100% UV protecting, shatterproof, anti-reflective and hydrophobic, helping rain and sweat slide off.

The Supernovas also come in a host of different colours, from boring old black and grey to smoky red with vibrant fluoro yellow arms.
