While the Bugstopper® Insect Shield® is designed for the lifetime of the garment, extremely prolonged use or aggressive washing may impact its efficacy. Ensure you are following the care instructions precisely. If issues persist, consider reapplying an EPA-approved repellent designed for clothing, though this is generally not necessary with this technology.

Check that the arm sleeves are fully unrolled and unbuttoned if applicable for maximum ventilation. Ensure the fabric is clean and free from heavy residues that might impede airflow. Washing with mild detergent and tumble drying on low heat should help restore breathability.

Gently try to work the zipper back and forth. Apply a small amount of graphite (from a pencil tip) or a specialized zipper lubricant to the teeth. Ensure no fabric is caught in the zipper track.
