Cleaning & Care Instructions: The bamboo material used to produce these sweatbands is very delicate, so try not to wring them out too vigorously. If the material snags in any place, just clip the snag rather than pulling any loose threads. Because the fibers are delicate, washing on a gentle cycle, cold or warm water (no hotter than 104 degrees F) is recommended. Some folks are extra careful and wash them in a mesh laundry bag. For drying, you can line dry or tumble dry low.
