Better pics of my mod
The extra top tabs were added, as was a no8 zip on the internal pocket.
Im very happy with this mod as it takes my umlindi from 30L stock, to 50L with the side pockets, to 60L with my tarapocket on the back, to 80L with my kifaru medium roll top pod on top. Makes it more versatile than it was.
Pocket build was done by me by removing the side panels and making a pattern out of paper. Putting the bellows pattern on top and getting the folds/positioning correct then cutting the bellows to match the side panel pattern. My guy just needed to put some edge binding on the top edge, stitch on the strap guides, install the grommet and stitch the panel back in. He had to detach the front panel from the top to get this to work but he is a perfectionist (based in SEAsia)
I honestly wish this was standard as its just a longer bottle pocket with deeper folds!
