This is a light splash bivy with a bathtub floor and a suspended bug net. It combines durable HyperD 300 on the floor for rugged waterproofness and a two fabric upper layer for breathability.
Cut the upper layer materials to match up along the printed pattern. Make sure to leave 1/2 inch overlap to sew multiple lines to join the fabric pieces. Cut the top layer about 10 inches wider than the bottom so the bugnet can be suspended.
Cut semi-circular pieces to adapt the top layer to the bottom width & sew the rounded side to the top layer at the head and foot.
Sew in a zipper to the upper layer.
Cut the bottom fabric to desired dimensions plus 6 in. on each side for a wall. Sew box corners in the bottom layer.
Join the top & bottom.
Add suspension loops of ribbon as desired.
Dark olive HyperD 300 for the bottom. Membrane 15 in green dragon scale for the top/foot end. Nanoseeum in green Dragon scale for the top/head end. 6 foot
