John-
I’m, sorry I just reread your post and realized your looking for pocket mesh for a pack.. . . I was thinknig jacket liner pocket mesh. I would agree with the Quest. It’s a nice 1/4 in hole that’s not to big or small. The last pack I made I used a nylon spandex blend I got at the rain shed. It adds some weight but I liked the stretch. It allowed me to seam pocket edges into the pack sides so the pocket could expand but still lay flat. see pics I really liked the way it worked out.
I’ve attached some pic of a pack I made last winter to use as a winter day pack it’s size is based off the breeze as well. I even tried the revirse adjusters on the shoulder straps. Interesting idea but takes some time to get used to them.
Again sorry about the mix up.
