DescriptionThe whole story▼
The Just1 J-STR in Union Red / White Gloss holds dual ECE 22.06 and DOT certification — the most rigorous approval standards currently required for road use in Europe and North America — making it a helmet you can trust whether you are commuting, touring or pushing on a favourite road. Its gloss red-and-white finish delivers a purposeful racing aesthetic without compromising a single gram of the safety engineering beneath.
Key Features
- ECE 22.06 and DOT certified: meets the latest international homologation standards for road and sport riding
- ABS outer shell manufactured in two shell sizes, pairing genuine impact protection with a precise fit across the size range
- EPS liner in two sizes ensures the energy-absorbing foam is correctly proportioned for every head circumference
- J.I.E.R. Emergency Cheek Pads Removal System allows first responders to remove the cheek pads rapidly and safely in an emergency
- Double-D ring retention: the most secure and tamper-proof chin-strap fastening available
- Protx2 antimicrobial inner lining is fully removable and washable, keeping the helmet fresh ride after ride
- Wide Vision visor with scratch-resistant coating and Pinlock 70 preparation for fog-free riding in any season
Safety Architecture
Just1 engineered the J-STR around a dual-certification philosophy. The ABS thermoplastic shell is formed in two distinct sizes rather than a single universal shell, so the protective geometry remains accurate across the full XS-to-XXL range rather than simply padding out one oversized structure. Inside, the EPS liner mirrors that two-size approach, calibrating impact energy absorption to each head volume. The Double-D ring buckle — long favoured by race scrutineers worldwide — eliminates any possibility of the strap releasing under impact load.
The J.I.E.R. system is a feature that genuinely matters. In a post-crash scenario, paramedics can extract the cheek pads cleanly without twisting or levering the helmet, reducing the risk of neck movement during removal. It is a detail that separates a thoughtfully designed helmet from a cosmetically similar but less considered alternative.
Comfort and Interior
The Protx2 antimicrobial treatment actively inhibits the bacteria responsible for odour build-up — a meaningful advantage on longer tours or during summer riding. The entire interior — cheek pads, crown liner and moisture-wicking fabric — unclips and goes straight into the wash. The ergonomically shaped cheek pads conform to a wide range of facial structures without creating pressure points, and the ventilation system channels fresh air through the shell to maintain a comfortable head temperature on warm days.
Visor System
The Wide Vision visor offers an expansive field of view that reduces the need to move your head at junctions and when lane-checking — a genuine safety advantage in traffic. The scratch-resistant coating preserves optical clarity over time, and the Pinlock 70 preparation means you can add the anti-fog insert (sold separately) for autumn and winter riding without any modification. A nose cover is included in the box to reduce buffeting and fogging at speed.
Fitment and Sizing
The J-STR Union Red / White Gloss is available in six adult sizes. Use a soft tape measure positioned just above the eyebrows and around the widest part of the skull. Repeat the measurement for accuracy. The helmet should sit snugly with even, firm pressure all around — if it rotates or shifts on your head, size down.
| Size | Head circumference (cm) | Inches |
|---|---|---|
| XS | 53–54 | 20.9 – 21.3 |
| S | 55–56 | 21.7 – 22.1 |
| M | 57–58 | 22.4 – 22.8 |
| L | 59–60 | 23.2 – 23.6 |
| XL | 61–62 | 24.0 – 24.4 |
| XXL | 63 | 24.8 – 25.2 |

“Two shell sizes and two EPS sizes at 1,520 g, with a double-D ring, emergency cheek-pad release and a fully vented chin bar — a proper specification for the money. Be aware of what is behind the score: nobody has measured this helmet independently, so those areas are left out of the total rather than guessed.”
