If you're the type to keep your luggage packing situation as light and simple as possible then you know exactly how much of a pain packing a suit can be. Porter and London-based Casely-Hayford have created a packable suit that's not only comfortable, but always ready to go. The two-piece suit combo is made from "Combat wool", a material that is said to be six times stronger than traditional wools and also has a polyester blend to make it stretchy. Both pieces pack into a custom, slim Porter sleeve that you can just throw into your suitcase and be on your way.
