Works great! I have two other similar products and this is by far the most powerful. Especially for the price! Shipping was quick and easy without issue.

I haven't used these products yet, the raincoat used before was very heavy. It's very inconvenient to put on. So I tried this raincoat, it feels great to put on. There is no sense of obstructing action. When I opened the package, I found a variety of raincoats in different colors, each of us can choose the color we like. I think we can take it with us on the field trip. Because it was raining hard days ago, it was I who carried a raincoat like this I won't get caught in the rain, I don't even feel it. It's a great feeling. A raincoat is long enough, it won't get your knees wet. That's not what other raincoats can do. So I suggest you take a raincoat like this. It won't take up your space and it will bring you convenience.

positive

Fits good. Has an inside mask to hold shape. Takes a bit of shifting around to get the right tightness and make sure you can see fully out of the mask. It’s really pretty and has some fur on it as well. Using for a kitty cat costume and works perfect!
