Basic HelmetAll basic helmets (Figure 2, next page) include the following components:• Helmet shell. The outer surface of the helmet shell has a smooth finish(with non-reflective black paint) and is free of obstructions to preventsnagging of parachute lines. The helmet shell includes snaps forattachment of visors, bump stops to hold stowed visors in place, oblongeyelets though which goggle straps are threaded, pile fasteners to securethe goggle straps, and inside snaps for attachment of a communicationscable on either side of the helmet.• Edge roll. The leather-covered foam edge roll is reinforced in the frontand rear of the helmet to facilitate attachment of night vision goggle strapassemblies.• Chin strap. The chin strap is designed for a snug fit and helmet stability.It is attached to the helmet on both sides with attaching hardware.• Nape strap. The adjustable nape strap provides stability and a snug fit atthe back of the helmet.The differences among the basic helmets are as follows:• Earcups. The helmet is supplied with one of two types of earcupsystems: the plastic earcup retention assembly, in which the earcupsare attached to the helmet shell with retention straps; or leather earpads,which attach to the inside of the helmet with hook and pile.• Suspension systems. The helmet is supplied with one of two types ofsuspension systems: the adjustable pad suspension system, whichprovides ease of fitting and air circulation; or the XLINER, which providesease of adjustment and simplified installation. Both systems are attachedto hook fasteners on the energy-absorbing liner inside the helmet.NOTE: If the helmet has an adjustable pad suspension system, the napestrap is laced through back of the rear pad. If the helmet has an XLINER,the nape strap has a nape pad.The table below shows these differences for each helmet part number.Helmet PartNumberSizeEarcupStyleSuspension Style03D11801-1 Medium/LargeEarcup RetentionAssemblyAdjustable Pads03D11801-2 Medium/Large Leather Earpads Adjustable Pads04D11905-1 X-Large WideEarcup RetentionAssemblyXLINER (1/2-inch thickX-Large Wide)04D11905-2 X-Large Wide Leather EarpadsXLINER (1/2-inch thickX-Large Wide)2
