DescriptionThe whole story▼
Certified to the rigorous ECE 22.06 standard and carrying DOT and CCC approvals, the Just1 J-STR Tactical Blue / White Gloss gives street and touring riders the triple-certified protection they need, wrapped in a sharp, high-gloss racing livery that stands out from the crowd. Whether you are commuting on a naked bike or covering serious miles on a sports tourer, the J-STR delivers confidence at every level.
Key Features
- ECE 22.06, DOT and CCC certified — meets the latest international safety standards for road and track use
- ABS outer shell produced in two shell sizes for a proportionate, precise fit across the full size range
- EPS inner liner also available in two sizes, ensuring consistent energy absorption regardless of head size
- J.I.E.R. (Just1 Emergency Cheek Pads Removal System) allows first responders to remove cheek pads rapidly in an emergency
- Double-D ring retention system — the most secure closure type available for sport and touring helmets
- Protx2 antimicrobial interior lining is fully removable and machine washable for lasting freshness
- Wide-Vision visor with scratch-resistant coating and Pinlock 70 preparation (insert sold separately)
Safety Architecture
The J-STR Tactical is built around a two-piece ABS shell that keeps proportions correct at every size, paired with a two-density EPS liner tuned to absorb and disperse impact energy efficiently. Achieving ECE 22.06 certification — the most demanding European helmet regulation currently in force — means the helmet has passed stringent rotational and linear impact testing. DOT and CCC approvals extend that confidence across North American and Asian markets. The double-D ring chin strap is universally recognised as the gold standard for retention under impact, and the J.I.E.R. system means emergency personnel can remove the cheek pads without compromising cervical spine safety should the worst happen.
Comfort Over Long Distances
Inside, the J-STR is lined with Protx2 antimicrobial fabric that actively resists bacterial growth, keeping the interior fresh on hot days and long rides alike. The cheek pads and crown liner are fully removable and washable, and the padding itself strikes the right balance between support and softness. A precisely channelled ventilation system draws fresh air through the helmet and expels warm air at the rear, so the helmet remains comfortable even after hours in the saddle.
Visor & Equipment
The large Wide-Vision visor maximises peripheral awareness in traffic and on fast roads. The scratch-resistant coating protects against everyday wear, and the visor is prepared for a Pinlock 70 anti-fog insert, available separately, making the J-STR genuinely usable in cold or wet conditions. A nose cover is included to reduce wind noise and improve the seal at the chin, and a helmet bag is supplied to protect the gloss finish during storage and transport.

How to Find Your Size
- Wrap a tape measure just above your eyebrows and around the widest part of your head, passing over your ears
- Take the measurement twice to confirm accuracy
- The helmet should sit snugly but without pressure points — firm, not painful
- If it rotates when you shake your head, size down
