WARNING
For helmet stability, always tighten the nape strap and the
chinstrap as snugly as possible when wearing the helmet.
Failure to do so may result in injury.
2. Have the crewmember tighten the rear of the retention assembly by
adjusting the hook-and-pile closure and tightening the nape strap
through the adjustment buckle. (See Figure 4.)

3. Have the crewmember fasten the chinstrap as follows:
a. If not already done, insert the snap end of the chinstrap through the
D-ring on the right side (as worn) of the retention assembly and fasten
the snap as shown in Figure 5, view A.
b. Feed the other end of the chinstrap through the D-rings on the left side
of the helmet.
c. Split the D-rings, loop the chin strap end back through inner D-ring, and
pull the chin strap through both D-rings as shown in Figure 5, view B.
d. Tighten the chinstrap to the desired tension. Once the desired tension
is achieved, the chinstrap can be fastened and unfastened via the snap.
