Computational fluid dynamics testing shaped every surface of the Ventral Air MIPS, and POC's engineering team used that data to solve a problem that plagues most road helmets: the tradeoff between aerodynamics and cooling. Traditional aero helmets seal off airflow to reduce drag, leaving riders overheating on climbs. Heavily vented designs breathe well but create turbulence that costs watts at speed. The Ventral Air threads this needle by channeling air through the helmet rather than around it, using the Venturi effect to accelerate airflow through internal passages while simultaneously reducing the helmet's aerodynamic wake.

The airflow system starts with large vertical intake vents at the forehead, drawing air into deep channels that run the length of the helmet. As air compresses through these narrowing passages, it accelerates and exits through rear exhaust ports, pulling additional air behind it. This creates active ventilation at both high and low speeds, keeping heads noticeably drier than conventional designs even during sustained climbing efforts. The aerodynamic shaping continues to the trailing edge, where a 22-degree angle manages residual airflow around the helmet exterior to minimize turbulence and drag.

POC built the Ventral Air using their Whole Helmet Concept, engineering protection, weight, and ventilation as integrated systems rather than optimizing each independently. A fully wrapped polycarbonate unibody shell bonds to the EPS foam liner, providing structural integrity that allows for larger vent openings without compromising impact resistance. The result weighs in around 260 grams in a medium, competitive with dedicated climbing helmets while delivering meaningful aerodynamic performance.... Read More
