It was not possible to check because there is no image of the folded state with the maker, but ... the structure that the frames do not overlap even in the folded state (= the state where the most shield is lowered). That is, the frame on the helmet side and the frame on the shield side do not overlap. The state in which it is raised by the frame is the most closed state. Therefore, since the shield is raised by the amount corresponding to the frame, the gap that involves the wind increases. Recommended products from other companies.
I used it for the bubble shield, but as the gap of the thickness of this product is made it began to involve the wind. I was worried about rattling and chattering during running, but here was no problem.
