DescriptionThe whole story▼
The Just1 J-GPR is engineered where the racetrack meets the road: a full-face helmet built around the proprietary S.D.C. (Sequential Density Construction) system, which layers materials of varying densities to absorb and dissipate both linear and rotational impact forces. Certified to UNECE 22-06 — the most demanding homologation standard currently in force — this matte solid carbon shell delivers race-grade protection in a clean, uncompromising finish.
Key Features
- S.D.C. (Sequential Density Construction) multi-density impact management addresses both linear and rotational crash forces for superior head protection
- UNECE 22-06 certified — meets the latest European safety regulation for road and competition use
- Shell constructed from genuine 3K carbon fibre, available in 4 shell sizes with matched 4 EPP/EPS liner sizes for a precise, tailored fit
- J.1.E.R. emergency cheek-pad removal system allows first responders to extract the helmet safely without risking neck injury
- PROTX2 antimicrobial technology throughout the interior liner inhibits bacterial growth and odour
- 5 intake and 6 exhaust vents plus an integrated ventilated back protector keep airflow moving at pace
- Hydration-pack ready: internal routing prepared for a Camelbak-style reservoir
Construction and Comfort
Four distinct shell sizes — each paired with a dedicated EPP/EPS insert — mean the J-GPR avoids the common compromise of padding out a single shell to cover a wide head-circumference range. The result is a more uniform energy-absorbing structure around the entire skull. The removable and fully washable interior lining uses PROTX2 antimicrobial treatment to stay fresh through long track days. A redesigned liner-retention net keeps the padding precisely located even after repeated removal and refitting.
The EPS-lined chin bar adds an extra layer of protection at the front of the face, while the double-D ring retention system — the benchmark choice for serious riders and race regulations alike — delivers a secure, rattle-free fit every time. An anti-fog Pinlock visor is supplied as standard, eliminating the need for an aftermarket upgrade before you ride.
Ventilation and Aerodynamics
Eleven vents in total — five intakes and six exhausts — channel fresh air across the head and out through the integrated rear extractor. The ventilated back protector works in conjunction with this system to reduce buffeting and heat build-up at sustained road or track speeds.
