The S2 vest
was designed with three small upper pouches while the bottom part is all
MOLLE compatible for attaching pouches (see below). The back panel can be used as
a "flat-back" when carrying large backpacks or when
in a
vehicle and can be used with a designated 30 liter detachable bag. The detachable bag has top openings for hydration tubes and radio cables, internal and external MOLLE webbing for attaching additional pouches and
a pouch for storing a helmet.
