Hey guys, do any of you own or have used a hit air vest or any other similar vest from another manufacturer? Going to be doing club racing this season and the boss (queenie) is pretty much mandating that I use one or don't race!!!! I've heard pretty much all good things and have been told if they were out years ago that the over the years injuries would have been way less substantial. They look constricting to me. Interested in your opinions. Thanks in advance......Alpinestars also makes a suit that has a built in air system but it's like a boat load of loot.
