The Yakima SkyRise is treated to be waterproof from the factory. Over time and with normal wear (related to extraordinary outdoor fun) the tent will benefit from some maintenance. We like the Nikwax products. Use diluted Nikwax TechWash direct for cleaning with a sponge. Rinse thoroughly. While damp, apply Nikwax Tent & Gear Solarproof Spray to refresh the coating and add UV protection.
