As seen in the photo, the material is like windproof fabric. I bought 2 in size 6 XL; for a large dog weighing 35 kilos (the dog with light-colored fur in the photo), it fits perfectly. For a dog weighing 50 kilos (the dog with black fur in the photo), it's a bit tight but can be closed.
Fast delivery, the material is thin, very convenient to carry in a hiking backpack in case of unexpected storms or rainy days that you didn't anticipate.
My dog is a 30kg golden retriever, and we had been looking for one that would fit him well for a while. Size 6XL fits him perfectly.
I have an 80 lb german shepherd and an extra extra large is only half the size for him
I took the XXL size and it turned out to be very small; my dog is a Border Collie, and I couldn't find any reviews for the dog's size.
