We shall see.
The way to secure it is not a clip, but a pass through.  I am using on my body armor I wear as a cop and I am having to use zip lock ties to secure it.  I do hope it turns out to be moderatly durable. Time on the street will tell.  If it holds up, it is perfect my my use of easy access to my readers for the limited time I may need them.
