We ride ATVs/UTVs in the Utah mountains where there’s lots of powdery red dirt and can be extremely dusty especially when passing or following other riders that kick up dust and there are often a lot of riders on the trails. We’ve tried several dust masks and these seem to be the best option as far as staying in place and keeping dust out. When we are done riding we take the plastic inserts out and throw them in the wash and keep them clean. We usually wear a baseball hat backward and then fasten the bandana Velcro such that the baseball hat bill keeps the bandana from sliding off and it stays in place.
