Why would anyone want to fly a Paraglider when they could fly a Hanglider?
A Paraglider folds down into a package the size of a largish knapsack and can be carried easily. Conversely, a Hanglider needs a vehicle with a roof-rack for transportation to and from the flying site, as well as appreciable time to set-up and strip-down. It’s also somewhat easier to learn to fly a Paraglider.
