DescriptionThe whole story▼

When safety certification matters as much as the ride itself, the Just1 J-STR Solid Matte Black delivers. Carrying triple homologation — ECE 22.06, DOT, and CCC — this full-face helmet is built to meet the most stringent international safety standards, wrapped in a clean, understated matte black finish that suits everything from the daily commute to an extended tour.

Key Features

  • ECE 22.06, DOT, and CCC certified — meets the latest international safety requirements for road use
  • ABS outer shell manufactured in two shell sizes for a precise, proportionate fit across the full size range
  • EPS liner in two sizes, tuned to absorb and distribute impact energy effectively
  • J.I.E.R. Emergency Cheek Pad Removal System allows first responders to remove the cheek pads rapidly in an accident scenario
  • Double-D ring retention system provides a secure, rattle-free fastening every time
  • Protx2 antibacterial inner lining is fully removable and washable, keeping the interior hygienic on longer trips
  • Scratch-resistant visor with a wide field of view, accessory-ready for additional visors or fitments

Safety First — Built to the Highest Standards

The J-STR's safety architecture starts with an ABS outer shell that comes in two discrete sizes, meaning every head circumference from XS through XXL receives a shell proportioned specifically for it rather than a single oversized shell padded down to fit. The two-size EPS liner mirrors this approach, ensuring the energy-absorbing foam is correctly positioned relative to the rider's skull in every size. The result is a helmet that functions as its designers intended, regardless of whether you're ordering an XS or an XXL.

The J.I.E.R. Emergency Cheek Pad Removal System is a feature that riders hope never to need, but one that can make a critical difference after a collision. By allowing paramedics to remove the cheek pads swiftly and without disturbing the rider's head and neck, the system supports safe on-scene care. The double-D ring chin strap closure completes the safety package with a fastening method trusted by professionals worldwide for its reliability and resistance to accidental release.

Comfort and Ventilation

Safety-focused construction does not have to come at the cost of wearability. The J-STR's Protx2 antibacterial inner lining actively resists the build-up of odour-causing bacteria, making it a practical choice for riders who wear their helmet daily. The entire interior — cheek pads and liner — unclips and goes straight into the wash, so the helmet stays as fresh on day one hundred as it was on day one. Padding is shaped to provide a snug, pressure-free fit, and the aerodynamic shell profile reduces buffeting fatigue on longer rides.

Visor and Equipment

The scratch-resistant visor offers a broad, undistorted field of vision, and the shell is prepared for accessory fitments should you wish to upgrade to a tinted or Pinlock-compatible visor at a later stage. A nose cover is included to help manage airflow around the chin area, and the helmet ships with a helmet bag for storage and transport without the risk of surface scratches to the matte finish.

Size Guide

To find your correct size, place a soft measuring tape approximately 1.5 cm above your eyebrows and measure the largest circumference of your head. Repeat the measurement once to confirm accuracy. The helmet should sit firmly with no pressure points. If you can rotate the helmet easily 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

Fitment and Compatibility

The Just1 J-STR is a universal full-face helmet suited to all adult riders. It is not vehicle-specific and is appropriate for street, touring, and everyday urban riding wherever ECE 22.06, DOT, or CCC certification is required or preferred.

“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.”
