Well, I haven't used it much but I have a first initial impression which is incredibly positive. Anyone can see it's thin, yes it's thin BUT it keeps you warm in the autumn and spring. For colder weather, you simply wear something underneath and a fleece jacket. Therefore, it is recommended for autumn and spring. I wore it for the first time in the Vouraikos Gorge with light rain in November. It performed WONDERFULLY. Not a drop passed through. I don't know how it would fare in extreme weather conditions. I consider it a perfect purchase for amateur (and not only) hikers and of course, a value for money purchase. I emphasize that I recently bought it, I don't know how long it will last but it seems like it will do well if you take care of it. It was recommended to me by a store and I realized how right they were. Don't take it as a regular size. It's not a shirt. I, weighing around 90 kilos with a height of 1.75 meters, went for the Large size. It needs the space inside so you can put on a jacket whenever needed. And now that its price has dropped a bit, I consider it an even better deal. Definitely try it first. I consider it a very good purchase even if it doesn't catch your eye at first glance. Oh, and it's super lightweight, dries quickly, and you can easily put it in your backpack. Of course, I will also use it in the city.
