Finding a tailor/seamstress/sewer who can work with nylon packs and gear isn't so easy. I have an old, well-worn Eagle 3-day assault pack that was not Camelbak compatible. I went to
Specialty Outdoors and contacted Penny Schwyn (
info@specialtyoutdoors.com) regarding modifying the pack so that I could use a hydration system with the pack. Penny did a fabulous job, took a few weeks, and charged me very little money. There are folks out there who do the work, and if you are clear in your instructions you will get good work.
