1.90 height 100 kilos. I took the XXL.
I wear the top part over a motorcycle jacket and I am very comfortable moving. It's okay.
The only problem with the bottom part is that when you sit, it is short on the legs, resulting in about 20 inches being uncovered (your pants get wet, that is). Only if you pull it down do you cover yourself at this point, but then it will restrict your movement in the crotch. This, of course, has to do with the construction and not the size because I am okay with the size both up and down.
4 and not 5 stars for the uncovered legs, because based on the price and waterproofing, it is okay.

The pants make you very uncomfortable. For delivery-type work, you suffer. It also gathers when you sit on the motorcycle, resulting in not covering the shoes and letting water in.
Average quality... the right base of the zipper lost some stitches after a while, causing it to hang about 3 centimeters.

I only used the pants and unfortunately I am returning it. The top part is huge and the bottom leaves about 20 inches of leg uncovered when the legs are bent. It didn't have any other issues. The water was enough and I stayed dry in the rest.

I got it bigger so I can wear it with my work bag on my back if needed. I am very satisfied with the money I spent. Over 10 uses so far in combination with waterproof gloves, you don't even realize it's raining. It has scratchy pockets so you can put it on and take it off without having to take off your shoes.

The zipper on the jacket broke soon and I went and changed the zipper, the pants sag after an hour in the crotch.

The first time the zipper broke without even wearing it. In the second one they replaced for me, the zipper broke again after five uses. They didn't replace it for me. Stay away and get something better. The one star is for the pants.

Whoever wears XL clothes should get the 3XL, whoever wears Medium should get the 2XL. It doesn't let in any water or cold

The zipper broke after the second use and I am not pleased. I fixed it and it has done its job in the rain that I have worn it in.

Very good value for its price. As a distributor, I wear it for several hours and I wasn't dry, but I wasn't soaked either. It did get a little damp on the clothes, which is understandable at this price. You get what you pay for, though, and for about 3 hours you stay dry inside. I highly recommend it. Also, I am 184cm tall and weigh 87kg, and the extra large size was perfect for me

For its quality and price (23€), it is value for money. Quite thick as a material and relatively heavy, although it has not been tested in rain, it is permanently in the motorcycle's trunk just in case. I appreciate that professionals (delivery, courier, etc.) might need something more expensive for everyday use.

As a set, it is very decent for the money. It didn't let any drop pass through in heavy rain, even though I was in the rain for hours (delivery person). However, I would like the pants to have a smaller opening at the crotch. This particular one has a huge opening, which makes it difficult to walk properly because it pulls you and restricts your freedom of movement. The jacket, however, is perfect. If they could improve the pants and add pockets, it would be 5/5.

Value for money! The size 3XL is great to wear over a jacket and pants. I usually wear XL in clothes. It didn't let any rain pass through, only time will tell.

I need it for a 15-20 minute commute to and from work, and I used it the day after I bought it and I was satisfied.
After reading the comments, I decided to get the 3XL size even though I wear XL. It fit comfortably over my clothes and jacket, and I didn't need to take off my shoes for the pants.
The lining inside helps with easy putting on and taking off because it slides.
I will come back with a comment if I try it in heavy rain

I only needed it once and it was good. It didn't let any water pass through.
The reason I didn't give it 5 stars is because it doesn't have a zipper at the bottom (ankle area), so you have to take off your shoes to put it on or take it off. Especially when taking it off while being wet, your socks get wet too.

For its price category, I find it very good. I bought it with the intention of using it for a one-hour commute to work and back. For this use, it has proven to be extremely adequate, and in normal rain that I have used it in, I stayed dry when I returned home. So I am satisfied with this purchase. As someone else mentioned below, the pants require some attention to sizing because I found them to be borderline good in 3XL when I wear size 40 pants at the waist. In any case, try them on first. I should mention that the pants do not have pockets (which personally doesn't bother me), but the upper part does have pockets.

Everything is good for emergency use, I have it and it is very good for a half-hour distance. But the pants are quite tight. Get one size bigger.
