I was initially concerned becasue when I got to Colorado and put it on my zipper opened and I could not get out of it. I am a 5'2 size 16 with thick thighs. This fits perfectly although a bit long but I cuffed them. They are extremely perfect for the snow they fit very well. When I tried them on the second, third and fourth time, the zipper no longer broke. So they are a keep for me. I do recommend them. I just recommend when you initially get them try them on and sit down and bend over to test the zipper and give. And I looked cute to!
