The Versatile, 3 in 1 FSP. The bag you didn't know you need. Starts life as a nut-ruck/fanny pack, coverts in to a plate carrier dangler and finally in to a backpack. The R40 version of the FS Pack removes the original front pocket and replaces it with a shelf that a Pelican R40 can be attached to. The case remains 100% usable while mounted to the FS Pack.
