There’s something badass about not running for shelter the minute it starts raining. It’s like, Be cool baby, ain’t nothin’ but a little H2O! Make sure you say that in a 70’s blaxploitation tone, too. But still, that coolier-than-thou ‘tude does leave your shirt soaking wet. Performance fashion retailer Outlier is ready to solve that issue with the Supermarine Rain Shirt, a water-resistant weave of 100% cotton fibers that swells up and seals when exposed to water, keeping the moisture out and your manly musk scent in. The cotton is an updated version of the fabric invented by the British to keep their WW II pilots alive in the North Sea if they got shot down–and, yes, to also preserve that manly musk scent.
