Trenchcoat "shoulder flap"?

[40kaas-nl]

Hello all, My first post here on SF after being an avid reader for quite some time

I have a question about a detail found on some trenchcoats; the "flap of fabric" usually located on the front right shoulder and secured with a button... Can anyone tell me the purpose of this "flap"l? Also see the picture (from Google, probably a women's garmernt). Regards, Kaas

It is for securing gloves

It also covers the open top corner of the flap to avoid rain getting in there.

I believe it was also known as a "gun flap"... make of that what you will.

That's my understanding, military origins.
But, I have yet to see anyone actually use them for this.

Thanks for the replies. I would never have guessed the flap was used to store your gloves!

Like J I thought it might help to keep the rain out...
