For more rollypoly options, Maxpedition brings us this backpack version. It uses the same great fold-up when not in use concept, however when deployed, this version is made to go on your back. Most of the pack is made of 420 D material while the base (PALS area) is 1000 D. As usual the main flap uses a velcro closure and the back has PALS for 2 short malice clips with a sleeve for belt mounting. A Siamese clip is on top for extra mounting options. As for something new, there are adjustable backpack straps which are routed through the opening of the pouch. When these straps are tugged on they assist with opening closure. An extra flap is also on the back of the inside to create a slim zippered pocket.
For uses, the Rollypoly Backpack makes for a good backup backpack. It can be attached to kit, put on your belt, or rammed into another pouch without taking up too much space. If you know you will need a backpack, I suggest just bringing a full one along. However, if you aren't sure, the Rollypoly Backpack is a good lightweight option that will stay out of your way until needed. For a small upgrade I wish loop velcro was on the main flap as seen on the Rollypoly Extreme. This allows for an easy way to get the flap out of the way when filling up the pack. Currently available in Black, OD Green, Khaki, and ACU.
