How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible tape measure.
It is important that the tape measure runs around the widest part of the head – only then will you get a correct result.
Place the tape measure at the front, about 1–2 cm above the eyebrows, and run it along the sides above the ears.
At the back, the tape must run over the largest part of the back of the head (not too low on the neck). The tape may run slightly at an angle – what matters is that it sits all the way around the largest points of the head.
Make sure the tape measure sits snugly but does not dig in. Measure 2–3 times for the most accurate result. You can then compare the measured value in centimetres (cm) with our size chart.
Tips for an accurate result
- Keep hair flat (e.g. do not measure over a voluminous hairstyle)
- Keep the tape horizontal, i.e. along the largest circumference
- Do not measure too loosely
- For values between two sizes:
→ usually choose the larger size (depending on helmet model / fit)
Important note on fit
The right helmet should fit firmly without causing uncomfortable pressure points.
A new helmet may feel a little tighter at first, as the inner lining adapts slightly over time.

The Nexx X.R3R Apex Carbon White is built from the shell outward with a singular obsession: material excellence. Its X-PRO carbon shell — composed of over 60% carbon fibre — delivers a shell so stiff and so light that it fundamentally changes how a helmet feels at speed, reducing fatigue on long track days and demanding road rides alike.
Key Features
- X-PRO carbon shell with over 60% carbon fibre content for an exceptional strength-to-weight ratio
- Weight of approximately 1,350 g ± 50 g — meaningfully lighter than comparable composite shells
- Air Dynamic System with 6 intakes and 4 exhausts, including innovative Speed-Flow chin ventilation and vibration-reduced channels for consistent airflow
- High-Visibility visor in scratch-resistant Lexan-PC with X-LOCK magnetic closure and an exceptionally wide horizontal and vertical field of view
- ECE 22-06 certified with Double-D-ring retention, magnetic strap fixation and Emergency Strap System for rapid cheek-pad removal
- X-Mart Dry interior liner — antibacterial, breathable, twice as fast-drying as standard liners, and fully removable and washable
- Three shell sizes across the XS–XXL range for a precise, performance fit
Shell Construction and Materials
Where many helmets use carbon as a marketing surface layer, the X.R3R X-PRO shell integrates it structurally throughout the laminate. The result is a shell that resists deformation under impact with minimal mass, so the near-zero dynamic weight sensation at high speed is a direct consequence of the engineering rather than a styling claim. The Apex Carbon White colourway celebrates that construction openly: the natural carbon weave reads through the finish beneath the crisp white graphic treatment, making the quality visible at a glance.
Race-Derived Aerodynamics
Nexx developed the X.R3R profile specifically for sustained high-speed use. The spoiler geometry is tuned to generate near-zero dynamic lift, keeping the helmet planted and neutral regardless of riding position. Reduced turbulence around the shell translates to a quieter, steadier head position — something long-distance sport riders and track-day regulars both notice immediately. Even aggressive body positioning and sudden directional changes produce no unsettling buffet.
Ventilation: Air Dynamic System
Six intake vents draw air actively through the shell, while four rear exhausts expel warm air efficiently. The Speed-Flow chin vent is designed to direct airflow across the face and up through the interior, complementing the vibration-reduced internal channels that distribute fresh air evenly. The system is tuned to perform at the speeds the X.R3R is built for — not just at urban pace — making it a genuine ally on warm track sessions and summer touring alike.
Visor and Visibility
The panoramic visor is moulded from high-quality Lexan-PC for optical clarity and scratch resistance. Its wide field of view — both horizontally and vertically — reduces the need to move your head to scan junctions or apex markers, keeping your eyes on the information that matters. The X-LOCK magnetic closure latches and releases with one hand, even in gloves, and seals firmly against wind noise and debris at any speed.
Safety and Retention
ECE 22-06 certification is the current European safety standard, and the X.R3R meets it fully. The Double-D-ring chin strap is backed by a magnetic secondary fixation to prevent strap flutter, while the Emergency Strap System allows paramedics or first responders to remove the cheek pads rapidly without compromising a rider's cervical spine. The highly absorptive shell structure dissipates impact energy progressively across the laminate.
Interior Comfort
The X-Mart Dry liner uses a moisture-management fabric that dries at twice the rate of conventional padding materials. It is antibacterial, breathable and ergonomically shaped to the interior profile of the three shell sizes. Every element — cheek pads, crown padding, liner — is removable and machine washable, so the helmet stays fresh through a full season of use.
Fitment and Sizing
The Nexx X.R3R Apex Carbon White is available in sizes XS through XXL. To find your size, measure your head circumference horizontally across your forehead and around the widest point of the back of your head. If your measurement falls between two sizes, select the larger size for initial fit — the X-Mart Dry liner will conform with use.

| 53–54 cm | XS |
| 55–56 cm | S |
| 57–58 cm | M |
| 59–60 cm | L |
| 61–62 cm | XL |
