DescriptionThe whole story▼
Spend a full day in the saddle and comfort becomes everything. The Just1 J-PGRF in Arrow Red / Matte Black is engineered around that reality, pairing a multicomposite fibre shell with a ProTX antimicrobial interior that stays fresh, dry and pressure-point-free hour after hour — all wrapped in a graphic scheme sharp enough to turn heads at any fuel stop.
Key Features
- Multicomposite Fiber outer shell produced in four shell sizes for a precise, weight-efficient fit across every head circumference in the range
- EPS/EPP Sequential Density Construction uses multiple foam densities working in concert to absorb and distribute impact energy more effectively than single-density liners
- ECE 22.06 certified — the current European homologation standard, accepted on both road and track
- ProTX Antimicrobial Technology interior lining resists bacteria and odour, remains hypoallergenic and is fully removable and machine washable
- Wide Vision visor delivers a broad field of view; scratch-resistant and tool-free to swap
- Pinlock 70 ready with Pinlock 70 insert included as standard, plus a Dark Smoke visor for sun-drenched riding
- J.1.E.R. Emergency Release System allows first responders to remove the cheek pads swiftly and safely without moving the rider's head
Comfort and Interior Fit
The J-PGRF is built for riders who put serious mileage on the clock. The sporty-yet-stable shell geometry holds the head snugly without hot spots, and the four shell sizes mean the padding never has to do excessive work to compensate for a poorly matched shell. Inside, the ProTX lining does three jobs at once: it actively inhibits bacterial growth, wicks perspiration away from the skin, and pops out in seconds for a proper wash. For longer tours in warmer months, that combination makes a noticeable difference by the third hour on the road.
Visor System and Optics
Just1's Wide Vision visor gives you a panoramic view across the full riding arc. The Pinlock 70 insert — included in the box — forms an airtight double-glazing effect that eliminates fogging in cold or damp conditions without any chemical treatment. When the sun is high, swap to the included Dark Smoke visor in moments; both visors click in and out without tools. The scratch-resistant coating keeps optics clear through seasons of daily use.
Safety Architecture
The multicomposite shell uses a blend of fibres to achieve high rigidity at a manageable weight, and Just1's four-shell approach means riders at the extremes of the size range still wear a properly proportioned helmet rather than an oversized shell with extra padding stuffed inside. The J.1.E.R. Emergency Release System is a quietly important feature: in the event of a spill, paramedics can detach the cheek pads via external pull tabs, reducing the risk of cervical movement during helmet removal.
How to Find Your Size
Measure your head circumference with a soft tape placed above the ears and approximately 1.5 cm above the eyebrows. Take the measurement two or three times and use the largest reading. The helmet should sit firmly with no pressure points; if it rotates easily on your head, size down.
| Size | Head circumference (cm) | Inches |
|---|---|---|
| XS | 53–54 | 20 7/8 – 21 1/4 |
| S | 55–56 | 21 5/8 – 22 |
| M | 57–58 | 22 1/8 – 23 1/8 |
| L | 58–60 | 23 1/4 – 23 5/8 |
| XL | 61–62 | 24 – 24 3/8 |
| XXL | 63 | 24 3/4 |
