"Do you find yourself looking for more storage options in your hammock? Well, look no further than the Sidecar! The Sidecar is a huge pocket that can be zipped onto any Chameleon hammock and be accessed from the inside or outside of the hammock."
 
The above wording is straight from Dutch, and his team. 
 
NB This Chameleon accessory only works with the Dutchware Gear Chameleon Hammocks and not other makes/models.
