Please pick your sizes carefully. No returns. The AIRLITE SPC (STRUCTURAL PLATE CARRIER) offers all the lightweight mobility of Crye Precision's JPC(TM) while providing the structural load support of Crye Precision's AVS(TM) & CPC(TM). At just over one pound for the entire system (including front flap and cummerbund- each sold separetely), the AIRLITE SPC is an ideal choice for all environments including maritime. It pairs with our patented AIRLITE STRUCTURAL CUMMERBUND that allows pouches to be mounted on both the inside and outside of the cummerbund and is compatible with our EXTENDABLE STKSS(TM) to reduce the load on the shoulders and back. The AIRLITE SPC sheds unnecessary weight and bulk while improving overall ventilation. PLEASE NOTE: FRONT FLAP AND STRUCTURAL CUMMERBUND MUST BE PURCHASED SEPERATELY. SEE "RELATED ITEMS."
