MATERIAL & CARE 70% Polyamide / 23% Polypropylene / 5% Elastane / 2% Silver Ideal care is machine wash warm, air dry. Wash after each use along with the clothes you wore outside, and avoid touching the outside of mask after use. These masks are NOT medical grade and will not prevent infection. For best results follow all CDC guidelines, including social distancing and hand washing. Please note that exercising while wearing a mask is going to provide a different experience than exercising without one. As is true for any cloth mask, when our mask gets wet through heavy perspiration, it will affect the mask's performance. All masks restrict the total amount of air that can enter the lungs on each breath, and ours is no different. If at any point during use you feel dizzy or lightheaded, simply pull the mask down around your neck when you can keep a safe distance from others, and breathe normally until the feeling subsides.
