Me and my Girlfriend are Zumba instructors. We purchased two of these to teach class. We put the bodypack receiver in a sandwich bag to keep them sweat free. Although the Mic is water proof, the bodypack is plastic and the electronics could be easily damaged. We bought waist holders from amazon which work best. We have tried two other brands that were cheaper but Shure is the best. Wish they sold a hard case like the older Shure handheld.
