You only NEED a bottom insulation system, if you didn't order the Super Shelter with it. Lots of options on this forum that you can read about: pads, quilts, etc.
Most eventually change their stock HH suspensions, but you certainly don't have to. Enjoy the hammock!
EDIT: You may not NEED anything else out of the HH Box, but spending much time on this forum will make you WANT a bunch of supplemental goodies. Have fun.
