Ever looked at your Large Ruck or other MOLLE backpack and thought there just wasn’t enough room for all your gear? Well the USGI Large Ruck Sustainment Pouch is the answer to the problem you may be facing. These large general purpose pouches allow you to add a good bit of additional room to any compatible backpack. They take a a decent bit of MOLLE webbing, but once they are attached they aren’t going anywhere. They have an adjustable buckled flap to keep everything stored secure, as well as a drawstring opening. The pouches will fit all your wet weather gear easily, and other items like MREs without any issues. Putting one or two of these on your pack is an easy way to expand space and they’ll fit on the back of most body armor too, for stuff and things.

    These sustainment pouches are much larger than I expected they do have many loose strings but it is overall an amazing product so far.

    With regards, Maximus

  2. Tereasa (verified owner)

    Sustainment pouches are very well made. Nice rugged material used for construction. I have one in multi cam and one that’s ACU. It’s a good place for mres, flashlight or anything else that you need to be accessible. Fits well on a large size rucksack.

  3. Adam Miller (verified owner)

    The molle fits on a panel 6 wide and 6 tall, this is perfect on the eagle industries hydration carrier and will leave you 2 or 3 rows on top depending on how you mount the bottom tabs (full weave or half weave)
