Besides a helmet's most important duty of protecting your head, versatility comes in at a close second with Bern's G2 Helmet. Its new design provides adjustable ventilation and all-condition protection. And, even better, it's all presented in a streamlined, lightweight package that's ready for whatever you throw its way.

As with all of Bern's helmets, the G2 was constructed with a deep, surround-style fit. This signature design flows down from the top of your head and behind your ears, which provides you with more coverage than the common sit-on-top style of most cycling helmets. This ultra-lightweight, low-profile helmet features Bern's revolutionary ZipMold construction, which fuses liquid-injected, high-impact foam to the polycarbonate shell. The result is a seamless, thinner layer of protection that delivers the same, if not better, protection-level of much thicker helmets. Individual fit is controlled by an internal 'micro-adjust' that allows you to dial in the perfect custom fit for your head.

The G2 was built with eight vents that operate on a slider system. This allows you to run the slider fully open for maximum ventilation, partially open, or closed. In addition to being able to manage the airflow, you also have the option of incorporating any of Bern's snap-in liners to the inside of the helmet. Essentially, this allows you to use the same helmet for year-round riding. Bern finished off the G2 with a removable visor, furthering your customizable options.

The Bern G2 Helmet is available in four sizes from Small to X-Large and in the colors Gloss White, Matte Black, Matte Grey, and Matte Slate Blue. It complies with EN1078, CPSC, AND ASTM2040 standards for safety.

Awesome helmet - saved my noggin

  • Familiarity:I've put it through the wringer

I've been wearing the g2 on an 11 mile commute to work in Dallas , Tx for approx.a year. The replaceable liner for summer and cooler weather was fantastic.

Where the helmet really proved itself was in a recent accident. On my commute, I managed to crash pretty severely. Broke my shoulder through and through, 4 ribs, bruised a lung and cut my forehead and face. I ended up in the hospital for 2 days but not due to any cranial injuries, no concussion or anything. The helmet cracked through from the temple to behind the ear. I'm sure a lesser helmet wouldn't have faired as well.

I only hope I can find it again in my size.

So glad you chose this helmet C!

Thanks for the review!
