This Thindust neck gaiter is super-breathable, making it ideal for biking, hiking, yoga or the gym. It stays up on your face without ear loops (maybe not so well if you have a small face), and the fabric regulates heat and humidity well, making it the most comfortable for exercise, or any activity where a traditional face mask obstructs your breathing. Because it is so breathable, it offers less protection (for yourself and others) than a traditional thicker face covering would. But if the alternative is taking off your mask, or putting it under your nose, it’s clearly the better option. It will help you comply with the law in places where facecoverings are required, and avoid the scorn of your fellow humans. It’s also great for breathing in dusty places, and providing a little extra warmth around your neck. Available on Amazon.com in white, green, grey, pink, orange, black or brown for $10-11, with Prime Shipping.
