GATH surf convertible helmet in very good condition. I believe it's a Large, but could me a Medium... I just don't recall. For sizing purposes, look at the web site below. I measured my head at 57cm, and this helmet is just a bit loose for me. It includes a removable visor, removable ear covers, extra foam padding, and the bags/sacks. I will leave the GoPro mount on it if I can't remove it easily.
These helmets are around $120 new, I'm asking $45.https://www.gathsports.com/productsingle.php?id=215https://goo.gl/photos/YvUjwFB41Q9xF3rT6
