This jacket is not advertised as functional jacket, but is quite functional: 1) The nylon fabric keeps (light) rain from; 2) The heated jacket and windproof; 3) it is still breathable, so you do not sweat it. I had the jacket at about 2 degrees and warmed sufficiently (at least for a short distance); but I had also at 18 degrees - and did not totgeschwitzt myself in it. The jacket is very light and looks afloat. She's like a pilot jacket cut with knitted elements at the cuffs and the collar (without incorporated hood). I would take the jacket in blue, because I think they are susceptible to dirt. Since yellow is of course very sensitive. Overall, the jacket acts not necessarily sophisticated and high quality, so I think the EIA exaggerated. You pay - like me - between 40 and 50, the price fits but. Those oversize 56 or smaller size the jacket were offered in the meantime for 29 !! This is of course a real bargain! From the fit the sleeve length is to be noted that the size regularly fails, but something short. However, I advise against, to order larger than usual.
