we didn't build another helmet - we built a system
At the core of every Revi helmet is ESA® Protection, an integrated impact-management system engineered to absorb and disperse energy across its structure. But protection alone wasn’t enough. We refused to compromise on fit, feel, or the small details that make you actually want to wear it.
From our precision fit system to removable, audio-compatible ear pads and moisture-wicking liners, every element is designed for riders who push limits.
ESA® Shock-Absorption System
Traditional helmets rely on a single layer of EPS foam - it compresses once, then stops absorbing energy. Real crashes aren’t that simple. ESA® is an engineered system co-molded into the helmet’s core, designed to manage impact energy. It responds dynamically - soft at low forces, firm when energy spikes - absorbing and dispersing impact across its structure for consistent protection from small knocks to big hits.
How ESA® Reacts Under Force
ESA® is an engineered layer that manages impact energy through progressive, non-linear deformation. Under force, it compresses softly at low loads and stiffens as energy increases - absorbing and dispersing impact across its structure. Unlike traditional EPS foam, which crushes once and stays deformed, ESA® recovers after impact to maintain consistent performance.
how it's different
ESA® isn’t an add-on - it’s built into the helmet’s core architecture. Integrated with the hybrid shell and precision fit system, it works as one to manage energy more intelligently, reduce peak forces, and do it all without extra bulk or weight.
Protection Doesn't Stop Here
ESA® is designed to manage impact energy during a crash. To create a more complete approach to rider protection, Revi helmets also integrate Mips technology to help address rotational motion from angled impacts.
