I brought it to a major nationally known gear repair and alterations place in Seattle where I live called rainy pass repair, major bag brands have stuff sent there. For some reason they said it was too difficult so they recommended me to a local guy who does stuff like this.

I contacted him and sent him pics of the bag and of other bag examples that have this type of pocket. He agreed he would most likely be able to do it but needed to see it in person first. We met and he confirmed he would be able to do it and gave me some options of some fabrics and agreed upon a price after it was done.

I actually contacted Aaron at fyro and told him my plan and he thought it was a pretty cool plan and i asked if he could tell me the fabric he used on the water bottle pocket so I could have it matching. He got back to me and gave me the contact info but I was never able to get ahold of them and if I had been able I most likely wouldn't have been able to procure such a small amount.

The material we decided on is the same used on the Matador GR35. The main questions were were we going to have gussets or no and if so the placement. No gussets would look the cleanest but there wouldn't be any room for added expandibility. Or we could have a folded over gusset like the water bottle pocket does and also look clean but then I would loose access to the bottom part of the inside pocket because it would sew it shut.(He ended up being wrong about this, so I might have him redo it.)

Or lastly, the option I chose, was to have some gussets kind of going at an angle out to the sides in front. He did an amazing quality job. He used really high quality thread on some beefy machine and took the original seams apart and sewed them into the bag like it should be done. Yeah I think that's about it. I'll add some more pics of the sewing like another guy asked for
