Protocol Zip Jacket
Description
The Intent
A study in modular layering and transitional architecture. The 022 Protocol Zip is engineered for the spaces between destinations. The structured stand collar provides a clinical, protective frame, while the two-way zip allows for absolute control over the garment's drape and silhouette. Designed for the Calton Brown man who treats transit as a discipline, it bridges the gap between premium leisure and utilitarian function.
The Specification
-
Material: Heavyweight brushed-back cotton blend with a matte exterior finish.

Care
Every CB garment is built to last. The weight and finish require a considered approach to care. Cold wash, inside out, on a gentle cycle. No tumble dry. Hang or lay flat to preserve the structural integrity of the fabric. Avoid direct heat on any technical shell or fleece component.
Correct care extends the life of the piece indefinitely. These are not disposable garments.

The Standard

We work directly with manufacturers to control weight, finish, and construction to a specification that premium retail rarely delivers at this price point. The standard is non-negotiable.
