Impact protection

Engineered like armor.
Worn like a watch.

Inside the dome sits an aerospace-grade honeycomb lattice. On impact, force is dispersed across dozens of cells and absorbed by the structure before it ever reaches your sensor.

Multi-point dispersionOne hit becomes dozens of harmless ones
Zero sensor contactFull clearance: no compression lows, no irritation
Soft-touch baseSkin-friendly flexible rim, breathable woven strap

Thoughtful by design

Four parts.
No compromises.

A swappable top cover, honeycomb shield core, comfort frame, and quick-adjust strap. The cover pops off in seconds for sensor scans, and snaps back on just as fast.

The unboxing

A first impression
worth keeping.

Every shield arrives in a crisp, minimal box: the Fayn CGM Shield, its woven strap, and a quick-start card. No plastic clamshells, no zip ties, nothing to wrestle.
