This concept is awesome and solves a huge amount of problems.
you could use shock cord for staps and hiking pant material
Problems Solved
1) no belt rub
2) no mid step pants adjustment
3) no pack rub
4) extra pockets on you chest between shoulders for camera ect
5) cord locks and adjustable shock cord to pull up pants and zip bottoms for stream crossings
My brother thought of this I thought what a great idea.
