AirVantage
I've got the Rukka AirVantage jacket.
I'll make comparisons with my Chilli heated waistcoat for ref:
Pros:
No need for electric supply or cords.
Will raise the temperature by about 2-8 deg Centigrade (rough estimate)
Looks smart(ish)
Can be worn off of the bike freely.
Is lined with the Outlast material, which acts as a temperature buffer. For example, if you were riding in the Alps during a nice sunny winter day and then entered a long tunnel, it would take the sharp temperature drop you encountered when entering the tunnel and even it out over about 5 mins or so.
Cons:
Not as warm as an electric waistcoat, so wont cover sub zero temps.
I found that the air bladders need topping up after an hour or so of riding.
When fully inflated, it adds about two inches to your chest size so need plenty of room under your top layer.
Also when fully inflated, is very stiff!
