Waterproof Shell Care
Keep your shell well.
You can and *should* wash and dry your shell. Dirt, sunscreen, campfire smoke and peanut butter smears can all degrade the durable water repellent (DWR) finish, a coating added to waterproof gear to help moisture bead up and roll off the outer surface. (Few sights are more satisfying during a downpour.) If you want your DWR to keep working well, show it some TLC (tender laundry care): Warm water, mild detergent, low heat. Wash, heat, repeat.

DWR RevivalMost waterproof/breathable shells on the market are treated with a Durable Water-Repellant finish (DWR) which keeps the outer fabric from becoming saturated so the breathable barrier can do its job of keeping you comfy and dry.
Remember, a clean shell is a happy shell. Be sure to wash your waterproof/breathable garments and regularly replenish their water-repellent coating. Drying waterproof/breathable fabrics on a medium/warm setting will help to renew the fabric’s durable water repellent (DWR) finish. After many adventures and washings, your waterproof/breathable garment will require more than a simple washing and drying to revive the DWR finish. When water no longer beads up on the garment, it’s time to turn to a spray-on solution which you can find at your favorite outdoor gear shop. |
