If you're going to toss your favorite puffy or down sleeping bag into the wash, you might as well give it a spritz to keep that cherished down protected from wet weather. Granger's Down Wash + Performance Repel includes a way to clean your down-filled gear, and then add a water-repellent finish. After all, if that soft, fluffy stuff gets wet in the field, it loses those nice lofty insulating properties. Make sure you toss your jacket or bag in the dryer after cleaning it, just to rejuvenate the loft.
