There are several construction means to achieve RWW.
One make method is hubless inflatable with internal fabric walls; the entire corpus is packed into steamlined hybrind basebar with cable axis.
Another make method is longitudinal accordion with internal string spoking; the corpus reduces by the accordion build and then also folds to form a round cross-section .
Both makes use a trigger to release CO2 cartridge and/or redundant method for pilot-power to inflate upon failure to trigger the CO2 cartridge.
A third make method is to have the RWW fully deployed at all times. Such all-time RWW tolerates the profile drag during the entire HG flight.
Recommended: Also have skis upon which may be instrument panels.
Status of RWW: experimental
Notice that RWW inflated could act as a significant float in case of landing in water.
