CompressBag is supplied with your Progress harness. Additional bags are available to accommodate your additional gear.
Pack your folded paraglider in the conically shaped COMPRESSBAG. After closing the side zips you can squash the air out of the bag, and reduce the glider volume considerably. This will leave enough room in the rucksack for clothes and instruments. Put the COMPRESSBAG in the top end of the rucksack and pull the rucksack side flaps up around the glider to hold it. The zips will then be easier to close. Then push the COMPRESSBAG down when both side zips are done up and the rucksack is horizontal.
