I should note as others have noted that this IS a heavy pack. I'd never use it on a waist belt. If you are thinking of using a lightweight vest (like a hydration pack vest) like I do then this is an excellent choice and you will not notice the weight at all.
For waist clip/belt use I would not recommend it.
This is the pack I use: https://www.amazon.com/gp/product/B06XF27TY5/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
