Persol have always held an appeal for me. And how could they not? Their classic lines and quality crafting, true to their 'hand made in Italy' labelling, easily distinguish them from so many other pairs of sunglasses available to the savvy shopper. When driving, it's often a pair of Persol 2902s, in mock tortoiseshell, that I don. For this summer, however, I've been on the hunt for a new pair. Not that the 2902s have reached their use-by; I just need something that folds down smaller. And the genius of Persol's folding frame provides just that. Luckily for me, they've also just released a special edition of one of their most iconic pairs and Steve McQueen staple: the Persol 714.
