DescriptionThe whole story▼
When every fraction of a second counts on track and every movement must be unimpeded, the RST x D3O Ghost Split Chest delivers CE Level 1 certified protection in what D3O describe as one of the thinnest, most breathable chest armour solutions available. Built for riders who demand race-ready safety without the bulk that compromises riding position or body movement, this protector is engineered around D3O Ghost technology — a system developed specifically for ultra-low-profile impact protection in high-performance motorcycle apparel.
Key Features
- D3O Ghost technology — ultra-thin, flexible impact protection purpose-built for performance riding
- CE Level 1 certified for confirmed, tested impact attenuation
- Split Chest construction with a winged, tapered design that extends rib coverage beyond a standard chest plate
- Open Impact Print Geometry with a Lycra backing layer for natural body conformity and unrestricted movement
- Exceptionally thin profile and outstanding breathability — engineered for extended track sessions and long touring days alike
- Fit-and-forget comfort: once seated in your jacket or suit, it disappears into the ride
D3O Ghost Technology: Performance Without Compromise
The RST x D3O Ghost Split Chest uses the D3O Ghost platform — a construction that prioritises minimal thickness and maximum airflow without sacrificing the impact management properties that make D3O a trusted choice across motorsport. The open Impact Print Geometry is the key: a structured yet pliable lattice that moves freely with the rider during aggressive track inputs and high-lean cornering, then performs under impact when it matters most.
The Lycra rear backing keeps the protector positioned correctly against the chest without adding stiffness or heat retention. The result is a chest guard that genuinely complements the ergonomics of a close-cut race suit or sport jacket rather than fighting against them.
Winged Split Chest Design and Rib Coverage
Unlike a flat, single-panel chest piece, the Ghost Split Chest uses a winged, tapered construction that wraps beyond the sternum to provide additional coverage across the rib area. For track riders who may be bracing against a fairing or tucking tightly behind a screen, that extended lateral coverage is a meaningful advantage — protecting a zone that standard chest armour often leaves partially exposed. The split format also helps the protector flex with the natural movement of the ribcage through a full range of riding positions.
Breathability for Track and Long-Distance Use
Heat management is a genuine concern on circuit and on longer road tours. The open-cell Impact Print Geometry actively promotes air circulation across the chest, reducing heat build-up during sustained physical effort or warm weather riding. For riders who wear a chest protector every time they ride — not just on special occasions — that breathability is what makes the difference between a protector that stays in the jacket and one that gets left at home.
Fitment and Compatibility
The RST D3O Ghost Split Chest Protector is designed to fit into the chest pocket of compatible RST jackets and one-piece race suits, as well as any other motorcycle jacket or suit with a standard chest protector pocket sized for a D3O Ghost format insert. It is equally suited to track day use, sport touring, and everyday riding. Riders seeking to upgrade the chest protection level in an existing garment will find this one of the least intrusive options currently available.
