I found a matte navy Giro cycling helmet this afternoon around 3:15 pm by the Lakefront Trail entrance near Oak Street Beach in Chicago. It's a size M, with a white stripe pattern and a small scuff on the left temple. Inside, someone wrote the initials 'DP' on the red foam pad. The chin strap is present and the buckle works. I picked it up from the pavement near the bike racks along the path, hoping to help the owner get it back.
