While I like the fact that this belt has no metal parts, the materials used are of very poor quality. I've had this belt for less than a month and it's already broken. The part right next to the buckle just came loose as you can see in the photo. The material I examined is some kind of foam and other particles, super thin. The description of "robust" is wrong. This belt is strong under no tension. Don't buy it. This is not a quality belt, you will end up losing your money.
