Thanks! It does have HeadLock, which is probably my favorite feature.

You can find different straps like that on Etsy. These are the specific ones I got: https://www.etsy.com/listing/1346524404/

I’ve gone through a generic metal one, the Holy Trainer 5, and now on a Cherry keeper which I’ve enjoyed so much that I’m getting it downsized. The Cherry keeper is the first one that I could wear all day without even noticing I was wearing it. It’s just really lightweight and comfortable, and I think the new smooth finish helps from the earlier rougher versions.
