The object
Jamie Cook invented the Release Layer System, a helmet component that releases a controlled layer during an angled crash to manage rotational loading. The tangible safety hardware offers helmet makers an alternative protective architecture as cycling and action-sports standards increasingly address rotational brain injury.
What Jamie did
Invented the Release Layer System, a low-friction protective layer intended to manage rotational forces in a helmet impact.
Why it matters
Cycling Weekly's 2025 technical report identifies Cook as inventor and describes RLS as a direct challenger to the dominant rotational-impact safety technology market.
Living-status check
Cycling Weekly published its person-specific report on Cook and RLS in September 2025, positive evidence he was alive in 2025.
