When you're out on the roads and need comfortable protection that performs well in all four seasons, you need the Bern Allston Cycling Helmet. Featuring advanced Zipmold technology for a thinner, tapered, lighter helmet, the Allston Cycling Helmet gives you a higher strength to weight ratio than EPS helmets. A removable performance liner system lets you adjust both the fit with the turn of a dial and your temperature regulation from warm to cold weather. With 16 air vents, you'll stay cool, calm, and collected on the road, and the low profile fit and feel keeps you comfortable for those long rides.
