I'm still noobish myself. I run a pair of ESS goggles and a 3m respirator with filters and rubber flaps removed for better airflow. I moved the strap that went behind my neck to on top of my head to loosen the seal. I'd like to get a face mask that will be compatible with my googles and a mich style helmet down the road tho. I'm thinking the mesh style ones would be nice for improved airflow.
