CAUTION
When donning or removing the
helmet, flex the helmet just enough
to clear the head. Excessive
spreading may damage the helmet.
12. Have the wearer grasp the helmet in
the earcup area and flex the helmet
slightly. Place the front of the helmet
against the FRP (marked on the
forehead in the procedure on
Page 6). Referring to
Figure 2-57
,
hold the edge of the TPL and the
nape strap pad with pull down. Have
the wearer don the helmet and rotate
the helmet rearward.
NOTE:
Holding the TPL and the nape strap pad when donning the helmet with a
heat-softened TPL will prevent the TPL from bunching up in the rear.
13. Have the wearer pull downward with his or her hands on top of the helmet until it is seated
firmly on the head. Lower the visor to check nose centering and clearance. Fasten the
chinstrap and the nape strap as tightly as possible, without causing discomfort, to optimize
the wearer’s peripheral vision. Have the wearer maintain as much downward pressure as
possible, without causing discomfort, for 3-5 minutes.
NOTE:
The TPL top should be compressed as much as possible; this will afford a low
center of gravity and long-lasting comfort.
14. Release pressure on top of the head and the remove helmet. Ensure that the TPL lies
smoothly in the helmet. Reposition the liner if necessary to maintain a ¼" protrusion at the
front of the helmet.
NOTE:
If the TPL is not properly fitted, reheat the TPL, and repeat the custom-fitting
procedure.
15. Remove the masking tape from the nape strap pad hook fastener.
16. Have the wearer don the helmet. Adjust the earcups; tighten the nape strap and the
chinstrap.
17. Perform a final fit check. No pressure points should exist; if they do, remove the TPL from
the helmet and repeat the custom-fitting procedure.
18. If the fit is still too tight after the TPL has been custom-fitted, select the next larger helmet
size.
19. If the helmet fits properly, proceed to Step 2 of Paragraph 2-4 (Page 27).
