I have the Dainese Smart Jacket. I picked it up a few weeks ago, when the SF Dainese store received their pre-orders. I commute daily on the bike and have been happy with the smart jacket so far.
I have used a Hit-Air vest since 2011 but thankfully have never had it deploy. The Dainese seems to allow more air through than the Hit-Air but I have not ridden with it on in really hot weather yet. I like not having the tether the Dainese vest to the bike and being able to wear it under my jacket.
With the Dainese you do have to remember to charge it every other day depending upon usage. To me the Dainese feels less obtrusive on the bike. However the Hit-Air protects you in areas that the Dainese does not, specifically the neck and hips.
Thanks for that. I'm not a fan of tethered systems or vests that go over my jacket, so the Dainese is one of the few options left. Curious to see how you feel after you use it in 90°+ weather.
