I recently purchased a Helite Tutle airbag vest. Typically I ride year round for all my transportation needs. Anything I can do to stack the odds in my favor should an accident happen I will look into. So far it is quite easy to use and I have not accidentally activated it, however you can tell my coworkers desperately want to pull the tether as I walk by. It will likely be a bit warmer in the summer, however I will know more after my fall trip where I will enjoy some warmer climates. In searching this site there were a few mentions wearable airbags, however not a significant write up. After riding with it for a few weeks I will follow up and let everyone know what I think.
