DescriptionThe whole story▼

The Just1 J-GPR in the Lorenzo Baldassarri Replica livery is engineered to feel as good over a long alpine tour as it does through the final chicane. Four shell sizes paired with four matching EPP/EPS liner sizes mean the fit wraps your head precisely — no dead space, no pressure points — so fatigue stays off the agenda from the first kilometre to the last.

Key Features

  • Four shell sizes with four corresponding EPP/EPS liner sizes deliver a tailored, individual fit across every head shape
  • S.D.C. (Sequential Density Construction) system combines materials of varying densities to absorb both linear and rotational impact forces
  • 3K carbon fibre shell keeps the helmet light without sacrificing structural rigidity
  • J.1.E.R. emergency cheek-pad removal system allows first responders to extract the helmet safely
  • PROTX2 antimicrobial technology built into the liner fabric fights odour and bacteria on extended ride days
  • Eleven-vent system — five intake, six exhaust — plus an integrated, vented spine protector keep air moving continuously
  • Removable, washable interior liner and a new lining-retention net maintain freshness and shape over thousands of kilometres

Construction & Comfort

Just1 built the J-GPR around a genuine 3K carbon fibre shell, produced in four discrete sizes so the shell curvature is never compromised by stretching one mould across the full size range. The result is consistent wall thickness and predictable impact behaviour whether you order an XS or an XXL. Inside, the S.D.C. liner architecture layers EPS foam of different densities: softer outer zones manage the initial rotational energy of an oblique strike, while a denser core limits peak linear deceleration. The EPS-lined chin guard extends this protection to the lower face.

Day-to-day livability is handled by the PROTX2 antimicrobial fabric, which suppresses the bacteria responsible for helmet odour — a genuine benefit for riders who log big daily mileage. The entire interior, cheek pads included, unzips and machine-washes, and the new lining-retention net keeps everything seated correctly when you reassemble. A Camel-Bag hydration port is already integrated, so long-distance riders can stay hydrated without stopping.

Ventilation & Visor System

Five intake vents and six exhaust outlets work together with the internally vented spine channel to pull warm air across the scalp and out at the rear. The anti-fog visor and included Pinlock insert eliminate misting in cold or damp conditions, while the included dark visor gives you an immediately usable sun solution without reaching for a separate shield. The double-D retention ring is the standard trusted by racing homologators worldwide.
