Here’s the truth: Dirt is the enemy. Not water. Not rain. Just filthy, grimy dirt. If you never wash your rain jacket, it will lose its waterproof mojo faster than if you washed it. Gross, right? All that oil from your skin and trail dust clogs the pores in the breathable fabric. Your jacket slowly turns into a sweaty plastic bag.
Patagonia doesn’t want you to be a sweaty plastic bag. They want you to wash it. It says so right on the tag. Even the most elite gear needs a bubble bath. Think of it like this: your jacket fights rain, wind, and your own body odor. It needs a spa day.
