I used the mesh one from Safermoto Hit-Air and i hope i never have to use it flying off the bike. Unfortunately, most of my crashes ended up with the bike staying with me and landing on my leg. I might have not adjusted the airbag cord to the proper length/tension so the airbag didn't deploy. I first bought the 2 piece black chest protectors but have upgraded to the honeycomb 1 piece version as the structure acts as a suspension and slows down impacts. The mesh on the elbow exteriors isn't as tough as I wanted them to be. And Hit Air should supply their jackets in more colors, especially hi-viz IMO. Overall though, I like the jackets.
