Yakima's SkyBox NX 18 once again takes cargo-hauling to a new level. The aerodynamic shape holds 18 cubic feet of gear-think camping supplies for a family of four or six pairs of skis up to 195 centimeters in length. SKS Locks, interior tie-downs, and secure installation hardware keep our precious equipment secure, and optimized hatch clearance makes loading both the cargo box and our vehicle easier.
