I like the concept on how the belt can be removed. I saw a similar design from a Malaysian maker but yours have wider foam with better hug on the hips. However, I used duraflex spider clips to attach the belt differently to my backpack so that I have the hip belt foam extended between my lower back and the packpack. It would be better if I send a pix. So, may be the foam can extend further is my proposal. Also, you are using one sided duraflex clip, maybe a double sided duraflex clip will allow the user to adjust the hipbelt attachment to the backpack. Just my idea. Note though that I haven't tried the hipbelt with a loaded back pack.
