The Granger's Outerwear Care kit includes a bottle of Performance Wash and a spray bottle of XT Waterproofer to keep your gear clean, odor free and water repellent. Granger's Performance Wash effectively cleans technical outdoor clothing to remove odors, optimize breathability and maintain water repellency. Great for use with down jackets, base layers and waterproof apparel. Bottle contains 6 capfuls of concentrated wash; 1 capful treats 2 base layer garments or 1 jacket. XT Waterproofer is ideal for waterproof clothing, soft-shell garments, insulated jackets and even sleeping bags after they have been cleaned with Performance Wash. XT Waterproofer is best applied to a damp garment; shake bottle and spray evenly onto the garment; tumble dry on medium heat. Recommended for use on Gore-Tex(R) and eVent(TM) waterproof clothing; both products are water-based.

This waterproofing agent comes with an easy-spray container that allows you to renew the water protection on hard shells, soft shells, insulated wear, and sleeping bags. It's safe to use on both Gore-Tex products and other waterproof breathable fabrics, and each treatment lasts for up to 10 washes.
The advanced spray-on formula of Granger's XT Waterproofer adds durable water and stain repellency to all outdoor fabrics and enhances breathability.
