Defunkify’s ACTIVE ODOR SHIELD EXPEDITION STRENGTH treatment kit is perfect for those who like to explore the world away from modern conveniences – like washing machines. Garments treated with the anti-odor shield resist stink so well you can wear your performance gear multiple days in a row without smelling funky. It’s perfect for that hike, long ride or camping trip. First, the ACTIVE WASH super detergent (included) removes stains, sweat, body oils and the built-up scum that cause persistent odor. Then ACTIVE ODOR SHIELD EXPEDITION STRENGTH coats the fibers with deodorizing molecules to prevent odor during and after wear. Just one treatment is so durable it will hold up through 20 washes – an entire season.
