This monochrome variant of the ULTRA // Black Echo Protocol Tee dials the intensity down visually while pushing the covert energy way up.
The red accents from the main version are removed, leaving behind a clean grayscale echo-wave symbol, ULTRA header, and tactical broadcast arcs.
The Black Echo Protocol is one of ULTRA’s deep-network disruption programs - a sonic interference pattern used to jam surveillance audio streams and distort OptiCorp’s listening tools.
In this stripped-back edition, the design feels even more like a classified technical diagram pulled straight from ULTRA’s internal schematics.
The neutral palette also makes this version easier to pair with layered fits or minimalist wardrobes while still carrying the core ULTRA lore.
Printed on the Stanley/Stella Creator, this UK edition uses 100% organic, Fair Wear Foundation certified cotton with a structured premium feel.
