We've made this waterproof trench coat for 10+ years, as why mess with something when it works and this works in the wet. Made in a technical, breathable, Italian cotton with bonded PU backing fabric, then cut and sewn in Portugal, it is hard to find garments made to this high standard.

Percival Auxiliary yellow binding and branding throughout. A jacket for life with a very reasonable price per wear when you wear it on the daily. This waterproof trench is part of the building blocks of every outfit of every winters day.
