Development notes / September 2026

A material is a beginning.

The difference between a promising textile and a proven garment.

A fabric specification cannot tell the whole story of a garment. A useful privacy feature has to work as part of something people can wear, close, carry and care for.

Our first development question

We are exploring a removable passive shielding pocket for a device. Material, seams, closure and everyday handling all belong in the evaluation. Its composition and performance are not final.

Evidence before a claim

The next steps are a physical engineering sample, usability review and a defined independent test scope. We will distinguish supplier material information from results on the finished assembly. There is no DUZ test report to publish yet.

Understand the limits

A device-isolation feature would also interrupt wanted communications while in use. It would not erase stored information or address other devices a person carries. We are not promising universal protection from tracking.
