I don't know if the soft protectors do the job (I hope I don't have to find out). Whether inside or outside the city, you sweat very easily. After a two and a half hour trip without a break, early in September, I got off completely sweaty. In the city, there's no discussion about it.. The zippers also seem to be of mediocre quality but for the money, it doesn't bother me, as long as it's safe.
The only thing worth praising is the nice design.

A first look.
I bought it on 1/11/18 for the price of 90 euros for summer daily use.
First of all, I would like to point out that the black color attracts heat. This means that in a stop with the sun above, the body will definitely start to heat up. Maybe in another color like beige, this phenomenon would be reduced. But let's be honest, black is more "stylish" and especially with a black motorcycle... "beauty is pain"! In motion now, with the motorcycle in the city and on a country road, it has been worn without the waterproof lining with 30+ C degrees and it is quite airy. Especially on the sleeves at the elbow and arm height, due to the perforated fabric, you will feel the airflow sufficiently, and at lower temperatures, my hands were getting cold and I had to wear the waterproof lining inside, which also cut off a lot of airflow. On the rest of the body, I did not feel heat but rather pleasant. The only downside was on the back where the protector is, where sometimes I would sweat. It has a very good fit at least for my body. The protectors on the sleeves are soft, to the point where you don't feel them at times.
Regarding the external zippers (pockets and central), I have not encountered any problems and they work well.
Do not wear it in winter, you will regret it unless you dress warmly.
So far, I consider it a very good jacket! Summer has arrived for good, so I will see how it goes in the next period.

27/7/19
After days of daily use, I note the following:
- I removed the back protector because I was sweating on the back with the heat, while without it, I didn't.
- I couldn't open the internal zipper, fearing that I would damage it. It is unused, stuck, and wrinkled, it doesn't open (unless it has a trick that I don't know).

Honest for the money it costs. I have had it for a month and have used it four times. It is not completely breathable and lightweight like other summer ones, but I think it can be worn comfortably all year round if you button it up and use the waterproof lining, we are talking about Greece and the south always. The protectors it has are soft like a sponge (hopefully I will never have to use them), I also find it quite stylish. Greek company, but made externally.. As for the zippers that the fellow traveler mentions, I haven't had any issues, but I haven't had to work on them much. Now we will also get a second one for the passenger! 4 stars because I would prefer it to be Greek-made as well!
