Probably better than no helmet, though my concern would be that this provides no real protection from abrasion for the face.

Motorcycle protective gear needs to protect from impacts yes, but abrasion is also a significant risk - slides from speeds over 100kph can be quite substantial in both time and distance - upwards of 5 seconds, and dozens of metres, pushing higher in different conditions.

This video of a slide in the wet made the rounds a few years ago: https://www.youtube.com/watch?v=DoYLKSYnrN0

Open faced helmets in general are a terrible idea. Close to half of motorcycle accidents will hit the part of the helmet that covers the sides of your chin. A scooter helmet or a brain bucket might keep you alive, but it won't protect the parts of your face you chew food and smell things with.

That extends to the rest of your body. Protective gear is the difference between a bruise and a scar.

Remember falling off your bike as a kid? At over 50 km/h with a 200 kg bike, you'll turn into a meat crayon.

As they say, dress for the slide, not the ride. Mine saved my life, and prevented a few scars.
