I am really impressed with the quality of this work belt. I bought this as a work belt as the 411 velcro started to wear out. The clasps are of very good quality and very strong. The material of the belt is very unique. This is a very hard mode but with some stretch. Not too much, you can squeeze it pretty well, but it still gives you some flexibility. It has clearly been thought and tested to find the 'right' amount of powerful yet flexible effects. I plan to buy more in other colors. I am rarely impressed by such products. It was a nice surprise for under $20.
