by Elliot Wolin

• OVERVIEW
• HOW DO I MAKE IT
• MATERIALS

• Two-person bivy sack cuts down drafts around our two-person quilt.  Center netting section eliminates condensation, 1.1 oz breathable perimeter coupled with staked-out and tensioned bathtub bottom stops drafts from all sides.  Drafts from above are typically not a problem, and the netting will block wind to a large extent.  Possibly might add 1.1 oz breathable top for coldest weather, connected to top with snaps or velcro.
• 1. Make four 5" corner sleeves from coated nylon packcloth or other scrap material
  2. Cut corners of silnylon, form bathtub incorporating corner sleeves
  3. Cut netting, round off top corners, sew perimeter zipper
  4. Cut netting filler pieces to square off netting and sew to zipper
  5. Sew top perimeter pieces to now rectangular netting center piece
  6. Sew top to bottom
