Comfortable and do the job

Work just like any of the dust masks you can buy at Lowes or Home Depot and probably do a better job at directing airflow. The vent on the side helps to prevent you from making the mask all wet from condensation and I like the additional padding on the bridge of the nose. Ear hooks stretch and fit perfectly while still being soft and don't irritate your skin. Have no complaints really... they're good masks for jobs that don't require a respirator and they're really comfortable to wear.
