The Bug Barrier Window Vent (No-See-Um 20x20 Mesh) is a finer-mesh version of our original vent, built to keep out smaller insects while still allowing steady airflow through your vehicle.
Designed for real-world use, this version adds tighter mesh coverage without restricting ventilation, making it a strong option for areas where standard screens fall short.
