Hi everyone! Sorry for the oversue update! I have been working late everyday constantly iterating on the hood design. Currently it is V2.2! It looks just like the ones they sell! It ia also made of Tyvek now. I can't wait ti ship these to some docotors who want to checm it out before it will be produced. This would've never been possible without the feedback of the team at 1 Million Ventillators, Front line medical workers, and my parents! I am so happy with V2.2! It is simplier, has higher visibility, easier to build, quicker to build, very comfortable, and has a better seal! In other words better then any of the balloon like horrible deisgns :p
