We recommend using a measuring tape to get an accurate size.

Measure around your head (in centimeters) taking the measuring tape just above the ears and about an inch above the brow line.

On any of our helmets online, you can hit the "size chart" button and figure out which helmet size is best for you!

Mips stands for Multi-Directional Impact Protection System, a safety technology designed to reduce rotational motion to the brain during angled impacts. Unlike traditional helmets that primarily address direct (linear) impacts, Mips-equipped helmets incorporate a low-friction layer between the helmet's shell and the head. This layer allows the helmet to slide slightly—typically 10–15 mm—upon impact, mimicking the brain's natural protective mechanism and helping to redirect rotational forces away from the brain .

Bern's warranty program covers all products purchased through our website from 1 year of purchase for manufacturer defects. Submit a request through our support portal.

We also offer a lifetime crash replacement warranty. If you take a tough spill; send us a photo of the damaged lid and the story about what happened; we'll do our best to send an exact replacement or comparable swap of a lid.

Please include proof of purchase.

We typically fulfill & ship our orders out within 1-3 business days out of our Plymouth, MA warehouse. Orders purchased late on Friday or over the weekend are fulfilled on the following Monday when we are back at it!

Here’s a general guide to when you can receive your order once fulfilled:

East Coast: 1-3 Business Days

Mid-West: 3-5 Business Days

West Coast: 5-7 Business Days

Our flip visors are compatible with

• Hudson
• Macon 2.0
• Macon 2.0 Jr
• Brentwood 2.0
• Major
• FL-1 Libre

Some helmets already come with the flip visor pre-installed (view product photography); but you may prefer a backup or having a different color. Feel free to mix it up and grab a spare if you desire.

You can manually initiate returns and exchanges through our portal here.

You will need to have your order # and the zip code chosen for the shipping address to find your order.

The customer covers shipping costs of the package being returned. If exchanging; once your original helmet is en route to our warehouse; we get a new order to begin fulfilling & packing to ship your way.

Reach out in our site's contact portal. There's a small chance we could still have what you need or we'll discuss a comparable replacement or solution to the best of our ability!

It’s the e-bike gold standard. NTA 8776 is a Dutch safety certification made specifically for higher-speed e-bike riding—think 28mph instead of 15. Your regular bike helmet? Not built for that. But Bern’s NTA-certified lids, like the Hudson, pack in 25% more protection while still keeping things low-profile and street-ready. More speed, more coverage, same signature style.

CPSC is the U.S. bike helmet safety standard—tough and impact-focused. EN 1078 is the European equivalent, with slightly different testing methods and impact thresholds. Both are legit, but CPSC generally requires a harder hit test, while EN 1078 leans lighter for urban and commuter riding. Bern helmets often meet both, so your dome’s covered regardless!

If it’s been in a crash or is over 3–5 years old, it’s time to replace it.Helmets age—just like your gear, your tires, and your knees. The foam inside breaks down over time from UV exposure, sweat, temperature swings, and general wear. After about 5 years, even if your helmet looks fine, it won’t absorb impact the way it’s supposed to. Newer helmets also come with better tech, so replacing means better protection and a safer ride.

The European Union standard for helmets for all non-motorized ski and snowboard helmets. Like cycling standard EN 1078, EN 1077 B certified helmets are assessed on stability and strap retention in an accident, as well as impact force reduction vs. not wearing a helmet. Where the EN 1077 B standard differs to reflect the difference in accident scenarios between cycling and skiing or snowboarding is EN 1077 B impact testing metrics for ‘cold’ environments reflect lower temperatures encountered in snow sports. It also adds a penetration test, where the helmet is tested to ensure foreign objects such as branches can’t reach through the helmet’s vents to the rider’s head.

ASTM F2040 is the safety standard for snow helmets in the U.S. It tests things like impact protection, strap strength, and how well the helmet holds up in cold temps. If a helmet is certified to F2040—like Bern’s Nino DVRT & Nina DVRT—it’s cleared for skiing, snowboarding, and winter sports where staying protected matters.

Multi-sport means your helmet isn’t just for one season or sport. Bern helmets are built to meet safety standards for activities like biking, skating, and snowboarding. Just swap the summer liner for a winter kit with ear pads and insulation, and you’re good to go—no need to buy a second helmet.

If helmets have CPSC/EN 1078 and also a EN 1077B/ATSM F2040 safety standard; the helmet is certified for both bike and ski use cases!
