The 80L Main Pack Scrim is crafted from durable 500D Low IR laminate, designed specifically to fit over your main pack, such as the USMC main pack with a total capacity of 5000 cubic inches (75 liters). It features a spacious main compartment of 3400 cubic inches and a lower compartment of 1600 cubic inches. This scrim is ideal for concealing bulky items like sleeping pads, enhancing your pack’s profile and helping maintain a low visual signature. Equipped with a long elastic shock cord, it weaves through laser-cut holes for a secure, adjustable fit. Beyond concealment, it simplifies the process of putting on and removing your pack and can be used to discreetly carry additional gear in the field.
