I bought this pouch to go with my Bamian 17 Pack, as well as with the original Modular Belt, in case I wanted to use it as a sling. As a pouch to complement the Bamian Pack this worked very well. In situations where I didn't want to fully expand my Bamian Pack and only needed to fit a few more items, I would add the L Pouch 2.0 externally to the Bamian molle webbing. It works very well in this role and I have found the compression/attachment straps on the bottom of the pouch to be super handy when I want to tether something like a bottle or rolled up piece of clothing to my bag without allowing it to make contact with the floor when my Bamian Pack is set down. I had my doubts for using this as a sling with the Modular Belt (1.0) but I was pleasantly surprised by the experience. I would pack out the whole bag for a weekend or week trip and then convert the hip belt and L Pouch 2.0 into a sling for short trips out when at my destination and it has more than enough space for all of the essentials. The fact that you can access the main compartment of the pouch from either the front or back zippers is really handy for getting quick access to the specific items you have inside. The pouch is made of the same high quality materials you'll find on the bigger backpacks and all of the zippers are quality YKK ones. If there is only one attachment you get for your Bagram or Bamian Packs, I think this is the one to go for, for it's sheer versatility.
I am very satisfied at present, and I will use it every time.
It feels great when both walking and running. It looks and feels durable. I enjoy using this to hold my phone, wallet, keys, and headphones while I go out for walks/runs!
I'm using it pretty much every day. Great versatile pouch.
