Motorcycle Airbag Vest Motocross Inflatable Vest 3D Breathable Mesh, Multiple Airbags Zipped Reflective Jacket (Color : Preto, Size : Large)

Was able to try this vest out at the track. I ordered a large and the Fftment seems small, wasnt large enough to fit overa race suit speed hump, but while riding, I could not even feel it.The material around the neck is soft, unlike other cheap airbag vests.Biggest issue is that it uses a 1/2 inch C02 fitting which don't seem to be readily available on amazon. My other vest is also 1/2, but it came with a reducer. If you try to use a reducer, it will not work as the puncture is too far away to reach. you need to cut the ends of the threads, then fit a 1/8 to 3/8 npt adapter and the puncture will reach.
