Moisture Barrier Assembly
The moisture barrier shall be a four (4) piece construction, two (2) back panels and two (2) front panels. These panels shall be joined using stitch type 516 to form seam type SSa-2 (Major B seam), and shaped to be compatible with the outer shell so as not to buckle, pull or otherwise restrict body motion.
The moisture barrier shall be sewn to the thermal liner at the edges only and bound along the edges with heat resistant neoprene poly/cotton and secured using stitch type 301, seam type BSc-1 (Minor seam), leaving no raw edges exposed.

Thermal Liner Assembly
The thermal liner shall be a four (4) piece construction, two (2) back panels and two (2) front panels. These panels shall be joined using stitch types 401 and 504 (516) to form seam type SSa-2 (Major B seam) and shaped to be compatible with the outer shell so as not to buckle, pull or otherwise restrict body motion.
