Several years ago now, over on NT-Owners.org, one of the riders had an accident. He was very experienced like most of the riders here are. He was leading a group of riders and all was going well till the road turned, and he didn't. He has no idea what happened and the docs said it wasn't one of those mini-strokes or TIAs. He almost died. All of his riding gear was in great shape. But if I remember correctly, he had 17 broken bones in his chest, a fractured vertebrae and a crushed vertebrae. Several months later, he was released from the hospital and over a year later, he was finally moving around doing some of the things he had done previously. I'm not sure if he ever rode a motorcycle again.
I didn't have to experience an accident like that to learn from his experience. I did my research and bought a Hit-Air airbag vest. The MLV-P in hi-vis yellow.

My first experience with it inflating was a bit embarrassing. I pulled up to a large busy intersection to make a right turn. I realized the light had just changed, but it would take a couple seconds for the traffic on the left to realize the light went green for them, and if I hurried, I could get out in front of them. I gave it some gas and let out the clutch...and a teenager with a skateboard walked out into the crosswalk in front of me. I grabbed the brake lever ...and looked up at the sky while I was laying on the ground. It's called physics.
As I'm laying there taking stock of what just happened, I realized I was laying on the edge of the curb. It was right against the back of my ribs...but I didn't hurt. My brain said that was unusual. It should be hurting really bad. Then...oh...the airbag vest went off.
Without the airbag vest on, in that 1 mph getoff...I should've had a couple broken ribs. The only thing hurt was my pride...and the airbag vest that looked so pristine before, now had a bunch of mud from the gutter on it. I bought another C02 cannister and for about $20 and five minutes of effort, it was back in order again.
FWIW, my thoughts are to get a vest, not a jacket. I wear my airbag vest with a summer jacket and a winter jacket. If the airbag was built into the jacket, I'd have to get two of them. And some of us are riding gear junkies and have quite a wardrobe.
Second, he pointed out some very valid points on the electronic airbag vests. Things like how the amount of inflation is next to worthless because in order for it to fit under a jacket, it can't have the volume you'd get on a tethered vest. And check the price on what it takes to send your electronic vest to the manufacturer. It's almost as much as I spent on my Hit-Air airbag vest. In the meantime, you don't have an airbag.
The cost of the Hit-Air MLV-P was a little over $500...a lot less than a trip to the Emergency Room would be.
