Signal shielding
Mailles
Pouches and shielded pockets that block radio signals from phones, key fobs and cards. Named for the chainmail in cotte de mailles, a garment that is also a cage.
Made to order · Limited commissions
Privacy-first clothing, engineered and measured.
Silver-shielded pieces, cut and made to order by a licensed electrical engineer. Tailoring and material as the luxury, shielding as the function, published test data as the proof.
The lines
Line names are working titles and are subject to trademark clearance.

Acoustic damping
A layered, decoupled pouch that reduces how much sound escapes or enters. Performance will be reported as a measured attenuation curve, never as “soundproof”.
Anti-recognition
Printed patterns informed by adversarial-clothing research. These aim to raise the cost of automated identification, not to make you invisible.
Electronics
Anything that carries a circuit. Every module is removable and every garment washable without it. All products are passive or low-power transmit only.
The atelier
COTTE does not make stock. Each piece is a commission, and the number we take on is kept deliberately small.
We start with what you carry and what you want kept private, then choose the piece and its shielded zones.
Each pattern is cut for you, with the shielded volumes, gaskets and closures designed as part of the garment.
Cut, assembled and finished to order in a deliberately small number of commissions.
Finished pieces are intended to be tested as finished items, with results shared with the owner.
Material
Silver is highly conductive, comfortable against skin and naturally antimicrobial, which makes it a better choice than nickel for anything worn.
Principles
Most shielding claims are for the material, not the finished item. COTTE publishes the numbers that matter.
Shielding numbers are measured on the finished piece, closure included, not on a fabric swatch. Results are published with the test method and frequency range.
Performance is re-measured after repeated fold and wash cycles, because shielding that fails after a month is not shielding.
A jacket has a neck, cuffs and a hem. COTTE garments build gasketed, fully enclosed pockets rather than promising a wearable cage.
No jamming, ever. Shielding only blocks signals to and from the protected volume.
COTTE is an early-stage concept. No commissions are being taken yet, and no performance figures have been measured.
