    Yes. Not only do our structures greatly surpass the standards in terms of energy absorbed we have also been independently tested, proving that HEXR is over 30% more likely to reduce brain injury than other helmets on the market:

  • Where do you do safety testing?

    Our test impacts were carried out at an ISO certified testing facility in the UK.

  • Have you done skin abrasion tests?

    Yes, we’ve used skin simulants to test if the Hexr structure causes skin abrasion. Our impact tests have shown that there is no visible difference between Hexr and standard foam helmets.

  • Do you offer a crash replacement scheme?

    Yes! We offer a 100% crash replacement scheme in the first year. If you have a crash while wearing your HEXR please get in touch with us at to arrange a replacement

  • Have your helmets been tested for rotational impact?

    Yes, we have performed independent testing at the University of Strasbourg by Professor Remy Willinger, a world expert in helmet design and head injury. The test method is based on real accident scenarios involving oblique impacts. HEXR performed the best in these results, outperforming the average by 30%.

  • Each helmet is unique, so how do you ensure quality control?

    Our helmets have been certified by the CE EN-1078 Safety Standard ensuring the product offers adequate protection during an impact. To ensure each unique helmet is certified, our design and structure generation process has also been certified, rather than just the final product. Each helmet is quality controlled in the UK before shipping.

  • Do you sell internationally?

    Yes we do.

    UK delivery is free, for Europe it is £10 and for the rest of the world it is £20.

  • How heavy is the helmet?

    Each HEXR helmet has a unique weight because it is custom-made. The typical weight of a medium helmet is 310 grams.

  • Which sunglasses are compatible with the ports?

    We have found that the majority of cycling specific sunglasses with straight arms (Oakley Jawbreaker, Radar EV, 100% Speedtrap, POC Do Blade, Crave) etc.) will work well. We recommend storing all sunglasses upside down.

    Unfortunately some larger sunglasses (Oakley Sutro etc.) or glasses with hooked arms (POC Nivalis etc.) will not work.

  • How sustainable is HEXR?

    The HEXR helmet is predominately made using plant based materials, Castor Beans to be exact. Typical foam material is made from Crude Oil and fossil fuels. HEXR is continuously searching for sustainable materials, helping to protect the planet. c

  • How breathable is a Hexr?

    Very well. The helmet is often used in hot climates because of its breathability. It is breathable because the helmet replaces foam material (used for insulation) with a honeycomb structure. This design has the highest surface area to volume ratio allowing warm air to dissipate from the head quickly.

  • How aerodynamic is Hexr?

    Approximately 7 seconds over a 40 km time trial when compared to both the Giro Aether and the Kask Protone. This data was produced by TotalSim,  using a simulation of a pro-rider on the drops.

  • Does the helmet account for my head swelling with heat?

    Yes. Each helmet has a small offset from your head to allow for swelling. Our comfort liner is particularly flexible to accommodate for swelling.

  • Is there an adjustable dial fitting system?

    Each HEXR helmet is custom fitted but will usually still require a ratchet system in order to ensure optimal fit. This is because the ratchet hooks under your occipital bone at the back of your head to help keep the helmet more snug.

    We also like to leave a little extra room in there to allow for your head to swell a little in the heat, or if you want to run a thick cap in the cold.

  • Can I wash the interior of my helmet?

    Yes. The interior padding is detachable and can be cool washed. The shell can also be detached and gently washed with water and mild soaps/detergents.

  • Are your helmets suitable for children?

    Our helmets are suitable for children aged over 12 years old. Please note that the head typically grows until the age of 21.

  • Where are the Hexr helmets produced?

    HEXR helmets are predominately 3D printed in the UK. The chin straps and shell are also made in the UK, and every helmet is assembled, quality controlled before dispatch from the UK.

  • What happens if I don't like my helmet when I receive it?

    Please get in touch with us at if you have any issues and we will respond within 24 hours.

  • If you haven't found your answer...?
  • I have a scanning cap already, can I scan without ordering?

    Yes. Simply select, "fit another rider" in the HEXR app. The details entered following the fitting will be attributed to the scan, regardless of the login. If you are yet to order the your head fitting data will be saved under your email address and automatically matched up when you buy a HEXR online.

  • What are the ideal lighting conditions for scanning?

    Please perform your fitting in brightly-lit room without any harsh sources of light. Similar to how you wouldn’t take a photo with the light behind your subject, a bright light source behind a dimly lit subject will give our algorithms a hard time.

    Doing your scan during the day usually makes for the best lighting, and away from small windows if they are the only source of light for the room.

  • How do I remove the ratchet system?

    To remove the ratchet first remove the read padding, this should expose the part of the ratchet cage that joins to the helmet. Next, gently pull the ratchet which should come away in the same way as the padding. The ratchet will still be attached by the two ball plugs. Pull these away from the underside of the helmet, you may have to use your nail or pull the cable firmly.

    The ratchet is designed to be removable so should be simple install and remove, if you have any issues please get in contact.

  • I have a very broad head, can you still make me a helmet?

    Yes. However please be aware the rim thickness of your HEXR might not be quite what you are used to in traditional helmets. While inside surface conforms to your head shape, giving a bespoke fit, the outside surface is matched to one of 6 shell sizes. This means the thickness can vary around the perimeter of your head.

    We will provide you with a 3D model of your HEXR before it is sent to print. You may notice that the front & back/sides of the rim are significantly thicker than the front & back/sides. At this point we will await your confirmation before going ahead with making your HEXR.

  • Will the middle plug of the helmet line up with the center of my head?

    Yes, for the majority of customers the center of the helmet will line up with the center of your forehead, even if you have an asymmetrical head.

    However, sometimes the outer shell can sit slightly off center as we need to find the balance orientation of the outer shell to the inner contours of your head. This ensures we balance the safety of your HEXR with the overall size.

    Head shapes vary from person to person, and no one's head is perfectly symmetrical. To learn more about all of the different head shapes and sizes we've made HEXRs for check out our blog post.

    Please be sure to check your head preview following your scan to make sure you are happy with how your HEXR will look and let us know if you have any questions.

  • How should I store my HEXR?

    When not in use, the helmet should be stored away from direct sunlight and sources of heat, we recommend putting it back in it's original packaging. Avoid leaving your HEXR in the car or anywhere else close to direct or indirect heat.

    Do not apply adhesives, solvents, stickers or paints that do not comply with the manufacturers specifications.

    Any alteration or intervention not provided for may impair it's protective function.
