Updates for 2020:

Updated for 2020, we evolved Protocol's fit and bi-swing back construction to adapt to more chest sizes while still maintaining a clean look and excellent range of motion. 

Built to navigate diverse customs and environments, the Protocol Jacket brings modern performance and casual elegance to a classic silhouette. Sophisticated tailoring combines a bi-swing back for enhanced mobility with the proven performance of lightweight and weather resistant Ventile. 

Unlined and expertly-finished, the Protocol features our signature taped buttons, functional cuffs, and double welted, tuckable pocket flaps. Ambidextrous interior pockets keep critical gear accessible and secure, while a single vent keeps you agile.

Having a tailor isn't quite the mark of a gentleman that it used to be, but a great fitting blazer still is.
