Delivery & Returns

The Bern Allston Helmet has proved to be one of this quriky US brand's most popular models, featuring 16 airy openings that allow for a refreshing stream of air to cool even the hottest heads on even the toughest rides. Made with a Zipmold lay-up to create a thinner, lighter urban cycling helmet with an incredibly high strength to weight ratio, the Allston tips the scales at a punchy 368g, and ships with the ever popular (and for this year BOA enabled for granular fit adjustment) removable comfort liner.

As ever, Bern helmets are season-adaptable; purchase a winter liner and swap out the included summer liner, and your Allston becomes a winter helmet-hero, suitable for cold weather rides or winter sports.
