[Thanks to Frank Colver for the mention of airtight zippers]
This topic is for exploring the use of airtight zippers in themselves with an eye for use in recreational hang gliding systems.
Airtight zippers were new to Frank and to me.
Apparently there are also "airtight two-way zippers" (humans getting out from inside hyperbaric inflated chambers?)
Half-baked HG motivations:
Zippered inflated harness parts for comfort, teardrop shaping, Safe-Splat,
Zippered airbeam.
Zippered HG bags inflated for rafting on water.
Tote bags zippered but inflated.
Zippered inflated pontoons for water landings. Later use as zippered tote bag.
Some cousin notions might arrive from study of http://www.balancedhealthtoday.com/hyperbaric-chamber-hbot-28inch.html
