I like this idea. The low cost and recyclable nature of this suits an item which needs to be disposed and replaced after an impact. It’s too tempting for people to reuse more expensive helmets that have been dropped/ or impacted despite that being incredibly dangerous.
I’m in the paper packaging industry. I see no reason why this can’t be as protective as a traditional helmet with the proper engineering and testing.
Though if I rode a bike a lot in a city, I’d just clip my helmet to my bag or belt.
I used to do this when I used to ride my bike to class in college. It’s clunky and awkward.
