How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible tape measure.
It is important that the tape measure runs around the widest part of the head – only then will you get a correct result.
Place the tape measure at the front, about 1–2 cm above the eyebrows, and run it along the sides above the ears.
At the back, the tape must run over the largest part of the back of the head (not too low on the neck). The tape may run slightly at an angle – what matters is that it sits all the way around the largest points of the head.
Make sure the tape measure sits snugly but does not dig in. Measure 2–3 times for the most accurate result. You can then compare the measured value in centimetres (cm) with our size chart.
Tips for an accurate result
- Keep hair flat (e.g. do not measure over a voluminous hairstyle)
- Keep the tape horizontal, i.e. along the largest circumference
- Do not measure too loosely
- For values between two sizes:
→ usually choose the larger size (depending on helmet model / fit)
Important note on fit
The right helmet should fit firmly without causing uncomfortable pressure points.
A new helmet may feel a little tighter at first, as the inner lining adapts slightly over time.

The Just1 J-GPR Raffaele De Rosa Replica is built for riders who demand all-day comfort and a precise, competition-grade fit without compromise. Four shell sizes and four EPP/EPS liner sizes combine to deliver a tailored fit that long-distance road riders and track-day enthusiasts will notice from the first minute to the last, while the 3K carbon fibre shell keeps weight in check across every kilometre.
Key Features
- S.D.C. System (Sequential Density Construction) absorbs both linear and rotational impact forces using multi-density materials, providing superior head protection in real-world crash scenarios
- Four 3K carbon fibre shell sizes paired with four EPP/EPS liner sizes for a genuinely personalised fit — not a one-size-approximation
- J.1.E.R. emergency cheek-pad removal system allows first responders to safely remove the helmet without risk to the rider
- PROTX2 antimicrobial technology built into the liner keeps the interior fresh during extended rides and back-to-back track sessions
- Five intake and six exhaust vents with an integrated, ventilated chin guard and rear spoiler manage airflow efficiently at speed
- Removable and fully washable interior lining with a new liner-retention net keeps everything in place however hard you push
- Camel-bag ready — a practical feature for endurance riding and hot-weather touring
Construction and Comfort
The J-GPR's shell is hand-laid in 3K carbon fibre, a construction that achieves an excellent strength-to-weight ratio while keeping the helmet at approximately 1,550 g (size M, ±50 g). The multi-density EPS architecture targets energy management across the full interior volume rather than relying on a single uniform layer, which means different impact velocities and angles are all addressed by the material best suited to each.
Inside, the removable cheek pads and crown liner are treated with PROTX2 antimicrobial technology. The liner-retention net — a refined detail on this generation — prevents the inner padding from shifting under hard acceleration or braking. The double-D-ring chin strap provides a secure, rattle-free closure that racing riders and safety-conscious road riders alike will appreciate.
The Raffaele De Rosa Replica Livery
This specific variant carries the official Raffaele De Rosa replica livery in a gloss finish, making it a visually distinctive choice for riders who want a helmet that reflects motorsport heritage. The graphics are integrated at manufacture rather than applied as decals, ensuring the finish remains consistent over time.
