I've just got one (jacket) as they are on sale at £93.My latest Gerbing has just packed up.
Its very light im a 42" chest and got a medium perhaps could have done with a small.! quite big fitting which is not want you want.
Controller on the bottom of the jacket and three heat stages,not as warm as the Gerbing but down on power I've just put my jacket lining back in and with the Blaze it will be toasty.
The connections are the same as Gerbing's so my hook up was ok just lost the Gerbing controller.
Glad I didn't pay full price only time will tell if its a relaible jacket,although BigD of this parish has had one for over a year with no complaints.
