To change hood sizes, first remove the hood currently attached to the base. To remove the attached
hood, first unlatch the cinch belt where the fabric is attached to the base. Then remove the fabric from its
frame structure by pulling the shock cord out of the aluminum frame. Finally, fold up the fabric you just
removed so that it can fit into one of the accessory pockets inside the carrying case. It is a good idea to
fold the fabric so that the tag identifying its size remains visible for future reference.
