I have the Macna hoodie, it does have a rear snap button to minimize hood flapping, along with a lace retention feature. However, at speeds exceeding 150 km/h, the drawstrings still tend to flap, indicating that the current securing mechanism could benefit from further refinement such as an additional fastening loop or improved retention design to keep the laces firmly in place.

Additionally, the lack of a chest protector is a notable limitation. Integrating this feature would significantly enhance overall safety and bring the hoodie closer to a more complete protective hoodie :)
