Helmets are perhaps the kings of diminishing returns — after all, every bicycle helmet sold in the US is subject to the same testing, and requires the same certification. What’s left after that is ventilation, fit, and, of course, style. Giro’s Savant has all three in spades, at a price that doesn’t require an immediate grams per dollar calculation. The Savant is secured with Giro’s Roc Loc 5, and features 25 Wind Tunnel vents to keep air moving into, through, and out of the helmet.
