So there are a LOT of mag pouches out there these days, but I thought these were worth showing for something different. The concept is somewhat like a FastMag using soft materials. The sides are made of elastic to keep pressure on the magazine while the insides have a generous amount of non-slip material. The end result is a pretty nice grip.
I wouldn't put them upside down or anything, but they are solid right side up. Unfortunately the back connection uses a bunch of wacky velcro webbing straps which is a bit bulky to give only so-so security. Having normal PALS webbing to allow attachment with MALICE clips or similar would be preferred. The front has PALS webbing, however I wouldn't use it to connect other pouches to as the weight would mess up the grip pressure. That said, one can still use the webbing to slip in tools for quick access. My main concern is durability as I am curious to see how long the elastic can survive, so I'll just have to keep beating on it to find out.
