Carry some bag that you can crush into your pocket, pull out bag, uncrush it, put helmet in bag.

Now you are just a person carrying stuff in bag like 90% of people in towns/cities.

And you want soda's, beers, snack bars, a box of food or something? And you want to save it for when not near town?
Well now you have a helmet bag to carry that stuff too.
