Under quilt is real easy....u just need a rectangle sleeping bag and some Paracord or equivalent. U use fleece saddle technology and bunch the corners and make a bridge on either end and clip the underwuilt bridges into the hammock biners and adjust until it makes a cocoon around the hammock... Clothes pins or chip clips and u can close it up if it's real cold.
