Great work guys, really impressed with the mylar bags. The low cost is
excellent, multiple bladders bring interesting characteristics, and
the reduced platform weight from using mylar vs. the thick
polyurethane on the SouthernBalloonWorks balloons might be
significant. Those $150-$200 SBW advertising balloons are very
reusable, but that seems less interesting if looking at $1.75 mylar
sleeping bags.
