RST x D3O CP2 Split Chest Protector | Part 103684

The RST x D3O CP2 Split Chest protector is built around one principle: no compromise between meaningful protection and all-day wearability. Its slim, low-profile split construction integrates seamlessly into motorcycle jackets and leather suits, delivering D3O's acclaimed impact performance without the bulk that discourages riders from using chest protection in the first place.

Key Features

• Lightweight build ensures no unnecessary added bulk inside the jacket, preserving freedom of movement
• Breathable construction promotes airflow and thermal comfort during long touring days or intense track sessions
• Versatile fitment suits a wide range of motorcycle jackets with a standard chest protector pocket
• Engineered for road riders, tourers and track-day regulars who prioritise certified protection alongside comfort

D3O Technology — Material Quality That Sets the Standard

At the heart of this protector is D3O's rate-dependent smart material. At rest and during normal movement the material remains supple and unobtrusive; on impact it locks rigid to absorb and disperse energy across the panel. This is not padding — it is an engineered protection solution, and it is why the RST x D3O CP2 Split Chest surpasses the demands of both CE Level 1 and CE Level 2 chest protector standards. For riders who choose their kit deliberately and expect it to perform when it matters most, that certification headroom is significant.

Slim Profile, Serious Construction

The split chest format divides the panel to follow the natural contour of the sternum and ribcage, sitting flat against the body rather than bridging across it. That seemingly simple design decision transforms how a chest protector wears inside a jacket. It eliminates the stiff, unyielding slab feeling associated with older mono-panel designs, and it means the RST CP2 fits properly inside close-cut sportswear and race leather suits without distorting the fit or restricting breathing.

Paired with a genuinely lightweight construction, the result is a protector that riders actually keep in the jacket rather than leave on the shelf. The slim build does not add visible volume to the chest area, which matters particularly for riders who wear tailored race suits or fitted touring jackets.

Breathable Comfort Across Every Riding Discipline

Protection that overheats its wearer becomes a liability on a long summer tour or a full day of track lapping. The breathable construction of the CP2 Split Chest allows air to circulate through the protector, moderating temperature and reducing moisture build-up next to the chest. Whether you are covering motorway miles on a touring day or working through a timed session at a circuit, the thermal comfort remains consistent and the protector stays comfortable across the full duration of a ride.

Fitment and Compatibility

The RST x D3O CP2 Split Chest protector is designed to fit the standard chest protector pockets found in the majority of modern motorcycle jackets and leather suits. It is suited to the following riding contexts:

• Road and everyday street riding — adds meaningful chest protection to any jacket already equipped with a protector pocket
• Touring — lightweight and breathable enough to wear all day without fatigue
• Track days and racing — meets the elevated protection demands of circuit use with its CE Level 2 capability

For specific jacket compatibility, check that your garment includes a dedicated chest protector pocket sized to accept a standard split chest insert. Consult the Inter-Pace team if you need fitment guidance for your jacket model.
