I've noticed more and more pouches available in the general marketplace. Wallymart now has some about 4 inch x 12 inch in different colors, Home Depo has a great 3 pack different size deal with a see-through mesh section (not a whole side). And from what I have used, they are very durable. I guess people are finally finding more uses for them. I still attribute it to know the TB pouches were on the market first though. Start another trend!
I recently purchased a well known (non-TB)brand zipped organizer pouch to use in my Synapse19 - it meets my requirements for greater internal organisation than any of the TB options but I cringe a little every time I pull it out .. the quality just doesn't elicit that little sigh of happiness that a TB pouch does....
and what the heck am I meant to do with that slightly crooked patch of loop ..... I am so not tacticool.
Even eager creek is making flat pouches now and also bigger bags similar to north phace but the durability didn't seem to be there when I looked at them.
