Nikwax Down DUO-Pack One Color, 10fl oz

"What Our Gearhead® Experts Are Saying: ""I rely on this system whenever a puffy or sleeping bag starts looking tired. Down Wash lifts grime without crushing loft, and Down Proof brings back that fresh, water-shedding feel you notice instantly in the field. It’s super easy to run both in a home washing machine, and every time I’ve used them together, the insulation dries closer to its original performance.""We turn to the Nikwax Down DUO-Pack when our favorite down jackets, vests, and sleeping bags need a full refresh before the cold season hits. Our favorite brands rely on advanced insulation structures to keep us warm, but those materials only perform at their best when they stay clean, lofty, and dry. The Down DUO-Pack brings both formulas—Down Wash and Down Proof—together in one system designed to restore warmth, breathability, and lasting water repellency. Down Wash removes the oils, dirt, and sweat that weigh down insulation and cause filaments to clump. Once the down is clean and lofted again, Down Proof steps in to add durable water repellency to both the outer fabric and each individual down plume. The result is a revitalized layer that traps warm air more efficiently and resists moisture far better in damp, variable conditions. Whether prepping expedition sleep systems or restoring a daily-wear puffy, this combo keeps essential down gear performing like new."
