How to measure your helmet size correctly: Measure your head circumference with a flexible tape around the widest part of the head, about 1–2 cm above the eyebrows and over the largest part of the back of the head. Measure 2–3 times and compare the value in centimetres with the chart.
Important note on fit
The right helmet should fit firmly without uncomfortable pressure points. Between two sizes, most riders choose the larger one. A new helmet may feel a little tighter at first as the lining adapts.

Welcome to the Wild Street. The Nexx X.WST3 is a streetfighter full-face with one of the most distinctive designs in the category — sporty character, high-tech Nexx features, and a safe, versatile helmet for everyday riding. Built on the X-Matrix2 fibreglass multi-composite shell, here in a matte black finish.
Key Features
- ECE 22-06 (UN), DOT (FMVSS 218), CCC (GB811:2022), NBR7471:2015
- X-Matrix2 (multiaxial fibreglass multi-composite) shell — a strong, light structure in three shell sizes (XXS–S | M–L | XL–XXXL)
- Aerodynamic rear spoiler — improves airflow, cuts drag and adds high-speed stability; it's a performance part, not just a styling cue
- Visor Recoil System — spring-loaded base side-plates automatically pull the visor against the twin-lip beads for a perfect, airtight seal; Pinlock 70 MaxVision fitted, clear + second clear visor included, plus a visor bag
- Internal sun visor, 18% larger — drops to just above the bridge of the nose
- Anti-Vibration EPS — a rubber layer between inner and outer EPS lets the inner EPS micro-move, cutting high-speed vibration for a smoother, more stable, safer ride
- Ventilation — 6 intakes / 2 exhausts, cheek-pad ventilation, the patent-pending Mid Airflow Chamber and the Air Cumbs cooling chamber for standout interior airflow
- F.R.S® Fast Release System — both cheek pads release tool-free for cleaning and safer emergency removal
- Metal micrometric ratchet buckle + X-LOCK magnetic catch; removable chin-strap covers; soft X-Mart Dry liner (removable, washable); night-vision reflectors; removable breath guard
- X-COM3 comms ready (Bluetooth 5.2); side action-camera mount
Contemporary Mastery
This X.WST3 uses Nexx's X-Matrix2 multi-composite fibre — a strong, impact-resistant construction that keeps weight low. Available in three shell sizes for a true fit.
Anti-Vibration EPS
The innovative Anti-Vibration EPS system places a unique rubber trim between the inner and outer EPS, allowing micro-movements that reduce the helmet vibration caused by high-speed air turbulence. The result is more safety, more head stability and a smoother, more comfortable ride.
Fresh Inside, Striking Outside
The interior blends faux leather, large ventilation-mesh inserts, dark reflective inserts and detailed stitching for a striking look. The soft X-Mart Dry fabric keeps the interior cool and dry. The Air Cumbs crown pad is stitched with a special alveolar mesh that forms a fresh-air chamber between the EPS and the padding.
F.R.S® Fast Release System
The patent-pending F.R.S® liner lets both cheek pads be removed at once, quickly and tool-free: lift the rubberised arms that lock the buttons on each side, slide the red buttons back, and both pads come free. Perfect for cleaning — and, crucially, it lets first responders remove the helmet from an injured rider easily and with minimal movement.
Sound & Camera
The new X-COM3 series integrates fully — earphones, battery, cable slots, microphone and Bluetooth 5.2 — in Standard and PRO (2.0 Mesh, Harman Kardon sound) versions. A side mount holds your action camera to capture life on the road.
Size Guide
The X.WST3 runs from XXS to XXXL across three outer shell sizes (XXS–S | M–L | XL–XXXL). Measure your head circumference around the widest part, about 1–2 cm above the eyebrows, and compare it with the size chart on this page. Between two sizes, most riders take the larger one.
