The spiritus systems elastic cummerbund is an excellent addition and option for the LV119 series plate carriers. It is slick, holds the carrier tight to your body, and can hold a variety of equipment so long as you can squeeze it into the elastic cells. The only con I have found is if you secure the elastic cummerbund onto your body while it is loaded with magazines, radios, or whatever else you carry on your kit, when you remove said items from the cells within the cummerbund, the elastic will get slightly looser resulting in a slightly less snug fit every time you draw a magazine or remove an item from the elastic cells. This is definitely not a con, as it is the nature of elastic, however, one way I have found to mitigate this minor issue is by securing the cummerbund and THEN loading in whatever items you desire. This is a great piece of kit and the elastic affords itself well for minimalist setups and can holds its own under heavier loadouts. Moreover, the elastic makes your carrier very comfortable to wear for long durations of time or under kit such as rucksacks and chest rigs. Although the cummerbund is not meant for the mounting of additional pouches, I have found that it is more than sturdy enough to support extra pouches if you can manage to attach them securely (get creative with elastic shock chord). Overall, I highly recommend this product for anyone that is looking to streamline their carrier or just needs a comfortable option for the range or training days.
