An extended-coverage trail helmet that puts deformable structure where side impacts actually land. Hexagonal crush pods over the ears, a deep occipital wrap, an integrated rear lamp and clip-on eyewear — modelled in Rhinoceros in a single day and rendered in Light Tracer.
Coraza — Spanish for armour — is a trail helmet concept that asks how far coverage can be extended before a half-shell stops feeling like one. Trail riders take their hardest hits low: temples, ears, the base of the skull. Full-face lids answer that, but most riders won't wear one on an ordinary loop.
The answer here is a deep-coverage shell that wraps the occiput and the jawline, with hexagonal crush pods over the ears — sacrificial, energy-absorbing volumes that keep the ear ventilated and hearing open while putting deformable structure exactly where side impacts land. An integrated rear light sits flush in the lower shell, and the brow accepts clip-on eyewear so glasses stow without a strap fight.
Built in Rhinoceros in a single day — one continuous modelling sprint from blank file to finished surfaces — and rendered the same evening in Light Tracer. The point of the exercise was speed with discipline: every surface decision had to be made once, correctly, the first time.
The upper shell keeps the language of a classic trail lid — deep intake ports, a low brow, a short peak — while the lower jaw section reads as a separate, softer-touch material zone. The hex ear pods are the signature: a structural honeycomb worn on the outside, open at the centre so the rider keeps situational hearing.
Rhinoceros — the entire helmet was surfaced in a single working day: primary shell and vent cuts in NURBS, the ear pods and jaw wrap in SubD, merged into one watertight visual model. No revision loops; the sprint format forces the proportion call to be right at sketch stage.
Light Tracer Render — a GPU path tracer used for all stills. The monochrome studio set, the soft gradient sweep and the emissive tail lamp were lit in one session, trading render-farm ceremony for immediacy.
