I wear this now:
2016 Hit-Ait Air Bag Vest. Approx $550.00 delivered.
Bikebone Motorcycle Safety and Security
There's two other manufacturers: Dainese, who makes a high-end model that leashes electronically to the cycle, and Helite. I wore the Helite vest, and at 4 lbs, it was almost twice as heavy as the Hit-Air (at 2.5 lbs). When it's on you, you can really feel the weight difference.
Supposedly, the airbag inflates in under 250 milliseconds. That's pretty fast. Like this: If it activates, and you're launching over a car hood, it will inflate before you reach the other side of the car hood. An eye blink is about 30 milliseconds. Thats fast.
This vest physically ties into the cycle frame via a lanyard with a quick disconnect. It takes alot of pulling force on the lanyard to active the vest. I've forgotten to disconnect before dismount many times now, and have not (yet) caused the vest to pop.
Thats the hardest feature for me: Remembering to "tie in" to the bike before riding away, and remembering to disconnect before dismounting.
But, I do enjoy the extra safety of airbag tech.
The companies offer this feature in coats and jackets, also. I opted for the standalone vest because I have different needs for pro, for different rides. I ride dirt and street, dual sport, ADV, and the '14R super sport.
So, I have a tether mounted to each cycle, and I "clip in" to my ride 'o the day.
The jacket and / or coat options become an expensive specialty garment. The vest can be worn over motocross armor to ADV air-weight armor, to full on rain gear ADV coat (when you might need it most, right?)
The choice to clip in while riding super sport street is a no-brainer. The same decision when riding 2-track or single track is a bit tougher. I decided to do it anyway for a couple reasons. It's where I take the most hits, it's where I take big hits if I crash (OK, not as big as a 70 MPH+ get off on pavement, but still, big enough to break bones, crush ribs, etc), and ... best of all, this thing is "rechargeable". This compartment I'm pointing at in the pic? That's a 60 cc CO2 cartridge, replaced for about 20 bucks delivered. That, and the bag folds back up into the vest for another use (not that I *want* another use...)
So, I'm posting this for my friends. These are now affordable. I rationalize it by thinking it costs about the same amount as one ambulance ride. Yeah, a bit morbid, but WTH, works for me!
My wife rides, too. We bought a 2nd vest for her. That's what I think of these things, I voted with my wallet to the tune of over a grand.
I feel safer already
