learn more below

Thinner, tapered, and lighter with a higher strength to weight ratio than EPS helmets.

13 oz.

Patented removable confort liner system allows you to go from warm to cold weather.

More than twice as much airflow.

Bern's signature low profile fit and feel.


"Bizarrely, before developing the Allston for Summer 2013, Bern Unlimited had never made a cycling specific helmet. Having owned previous models from the Massachusetts body-protectors in the past (most recently the company's Brentwood model, which I lost at a roof party in Brooklyn), I was kind of surprised by this fact myself. But for a freshman effort in the velo-specific category, the Allston is a star."

our most ventilated design

More than twice as much airflow than Bern's other leading bike models

made for cycling


"Staying cool in the summer is key, and even the breeze of riding on a bike usually isn't enough. And that's probably because there's a giant styrofoam cap on your head keeping all of that heat in, ensuring that, when you take it off, you look like you just got out of the shower. Bern's new vented Allston bike helmet is here to help. It's got 16 vents, it's extremely light (13 oz.), it has a removable liner for adapting to all seasons, and it even has a little bill. "
