I drove into the city this morning to pick up a few supplies from Seattle fabrics.
It's been a few years, but I dusted off my woefully under powered $100 Kenmore sewing machine. I'm pretty sure it hates me because all I sew is canvas, poly webbing, 500D-1000D Cordura, etc.
I did my GHB modifications. As a note, all these bags are pretty much the same design.
First off is the vertical cinch straps. They run 3/4 the way around the bag and incorporate the carry handle. If you used the straps to lash something on the bottom of the bag, said item would come loose when you unbuckled the straps as you have to to get into the bag.
I relocated the buckles and associated straps to the bottom of the bag, so now whats lashed to the bottom stays lashed to the bottom.
Another thing I didn't like was that if you used the cinch straps to lash something to the top of the bag the fixed carry handle would be off center causing the bag to hang oddly.
I added new straps in place of the now prepossessed ones, two new buckles and a new movable carry handle, now I can adjust the handle to always balance the bag.
And lastly, the front pocket has an internal pouch and a couple web pouches, but nothing on the flap side.
I added a couple 1" elastic bands creating 3-6 more places to secure small items.
I also dug thru the scrap bin at SF and found a piece of black 1000D cordura (free) that I think is big enough to make my stealth knife pouch, my SOG field knife should be here Monday, gotta love Amazon shipping.
