Very good, internally the seams are plasticized so that no water passes through them, although it is a bit tricky to fold it for storage in its case, the initial creases help (force) it to fold back to its original storage state. Even though I wear it over reinforced waterproof leather "boots" (not boots), it withstands the pressure - pulling so that the fabric does not tear, very good ventilation as well.
Flawless ALSO as a windbreaker so you can wear a light jacket and have freedom of movement.
I tested it thoroughly before evaluating it, I am very satisfied with its value for money, I highly recommend it...

Very good quality at an affordable price. It has nice details, such as elastic bands on the wrists, snaps on the bottom of the pants to close for more waterproofing. Also, there are areas with small holes (covered by the waterproof material) for the body to breathe. I liked it because it comes in a zippered case, for easy storage and transportation.
