The material is very pleasant and allows air to pass through, definitely not made of synthetic fibers. It fits well, with the hood and sleeves having a comfortable, relaxed fit, and everything is in the right proportions. I typically wear a size S (EU 36/38) and bought a size L for a more relaxed feel, which is ideal. The only minor issue is the string, which seems a bit low quality, but I still highly recommend this product; it's the best piece of clothing I've bought from this website!
