Sometime last year, there was a discussion on here about using a Tyvek mailing envelop to create a pocket magazine pouch. The idea was simple lightweight and low profile.
I was looking for something that would let me slip a couple of spare mags into my back pocket and at the time I could not really find anything off the shelf that I liked. So an idea was stolen and tweaked.
I did not have any Tyvek, But I did have some HEAVY mylar bags left over over from a project my company worked on along with a heat sealer for it.
So broke out the rotary cutter and spare mags, and came up with something that would fit 2 G43 mags and fit in my back pocket.
the bright and shiny tinman look was NOT want I was after, and the edges where a bit sharp. So I did what any good redneck engineer would do and broke out the duct tape, or Gorilla Tape in this case..
The Gorilla Tape not only made it less shiny, but also served to increase the durability. a second single mag pouch was made that did not get tape, and it started falling apart at the seams after a couple of months of use.
While not a true indicator of durability, this is after 8 months of daily carry, there is no wear or tear to speak of, the corners and bottom edge have rolled over a bit as they conformed to shape. You can also see where the corner where trimmed a bit to help fit the back pocket better and to help prevent premature wear on the pocket.
The snug fit in the pocket does make it difficult at time to remove the whole setup, but it does a great job at keeping the mags in a position to be drawn quickly if needed. and the flexibility in the pouch lets it conform to the body
