There is a new harness with built-in buoyancy that is using Kickstarter to get funded. I ordered one and if YOU do that soon you can get a nice discount from the regular price after the funding goal is met. Mine will not be delivered until September but since I know of no others being sold currently, that is better than never getting one. If you like this, please order one and help it get started. There is more info here: https://www.kickstarter.com/projects/580141349/integra-buoyancy-trapeze-harness
