Know how I avoid losing my mask? By wearing it on my face so it covers my nose and my mouth. When I do that, it's pretty much impossible to lose it.
It's really that simple. If you aren't being a douchenozzle and just wearing a mask when you notice someone approaching you- and don't get "surprised" by someone "suddenly coming up on you" and there you are out in public and not wearing your mask- you really don't have to reach for that mask at the last moment, "dive into your handbag" or your pocket to get that piece of cloth you apparently are only willing to put on for a few seconds at a time when you decide that it's absolutely necessary to suspend your imaginary Right Not To Wear A Mask Cause Freedom. Because you're already wearing it- as you walk across the parking lot and approach the entrance to the store, NOT carrying it in your pocket or your bag until you are five inches from that door. Because you're already wearing it- NOT only when the waitress approaches at the outdoor cafe, but the whole time you are sitting there because We're Trying to Get Through This you freaking Dicktards.
But I guess if you insist on whipping off your mask unless you are aware someone is within six feet of you, a mask with a built-in lanyard is a good idea. If you're not part of the problem, it's kind of unnecessary because, well, YOU'RE ALREADY WEARING THE FREAKING MASK.
And oh, by the way- funny thing about masks- they are very easy to just slip under your chin when you are outside and there really is nobody around. Even if you refuse to keep your nose and mouth covered like a good citizen, why the hell do you need a lanyard anyway?
Oh, and Copper again. Gotta mention that, too. There's nothing copper can't do. According to TV. Except keep you from losing your mask. So this one has a built-in lanyard.
