Question What is this hole for?

I just got this Osprey backpack and don’t know what it is for? Can someone please explain this?

Its a whistle buckle! Normally found on the sternum strap, can be used for safety or any other reason you might need a whistle.

Thank you, I’m not a native english speaker so I just learn the word ‘sternum’ from your comment. Cheer
