What makes the perfect raincoat? Well, it's gotta have coverage, a reasonable amount of style, and of course, it should keep you dry. Outlier's latest experiment does all of that and more with the Supermarine Zip Trench. The jacket is a classic trenchcoat that has been elevated in such a way that only Outlier can pull off. It's constructed with Supermarine F0 Cotton that uses a complex weave to not only keep you dry but it does this without the clammy feel of a technical fabric.
