Often a 'just in case' shell is a glorified trash bag. Not so with the lightweight, packable Showers Pass Men's Double Century EX Jacket. Built with Cocona Xcelerator fabric, this packable shell is not only waterproof, but highly breathable as well. Patented Cocona technology incorporates natural active particles that have microporous structures. These active particles have been tested to industry standards and have been found to enhance the breathability, dry-times, UV protection and odor management of performance fabrics. This means your core stays dry even if you're working up a sweat in the rain. Adding to the Double Century's ability to fend off wet weather are fully taped seams, compatibility with Showers Pass' Rain Hood (available separately), and a drop tail hem with cinch cord. While the Cocona Xcelerator fabric is highly breathable, Showers Pass still adds a back vent that allows air to flow freely if you've opened the front zipper. The Double Century has one zippered arm pocket, and plenty of reflective elements for low-light safety. It comes in sizes Small through XX-Large and two colors; White and Orange.
