Trench coats haven't changed much since their creation over 100 years ago. In fact, you'll notice that today's styles still resemble the coats Thomas Burberry designed for British officers in the Boer War. In other words, they last a very long time. Coats from Mackintosh are made from cotton bonded with rubber—meaning that they don't only look nice, they're actually waterproof. Unlike fashion brands, you're paying for the fact that this thing actually works, and will continue to for years. Plus, repairing it is an easy fix you can do yourself.
