The feathers it’s stuffed with are treated with a hydrophobic polymer known as perfluoroalkyl acrylate, developed by a company called Down Decor. So instead of absorbing water, the down inside the $US300 Mojave repels it. And while it doesn’t guarantee you’ll stay completely dry, the company claims the treated feathers will only absorb about a quarter of the moisture that regular down filling would. Which means your jacket will dry five times faster and be ready to warm you again in no time. [Brooks-Range via Popular Science]
