WARNINGS
The following are general safety warnings intended to call attention to fundamental performance
limitations and areas of the helmet where proper usage must be followed. Failure to adhere to the below
instructions and warnings could result in serious personal injury or death to the wearer.
This helmet is designed to protect the wearer against a specic range of projectile threats while
benetting from a minimal overall weight. This protection does have its limits and will not protect
the wearer against all threats. Certain threats may exceed the helmets capabilities and cause serious
injury including severe brain damage and death. Refer to helmet specications for performance
related data.
It is important to note that certain regions of the helmet provide less protection than others.
Specically, this helmet shell is not intended to protect against impacts that occur within 1 inch of
any peripheral edges.
Inspect the helmet before and after EACH use. Do not alter the helmet in any way.
This helmet is not to be relied upon to protect the wearer from falls from motor vehicles or bicycles,
or for similar activities.
Fit problems, such as excessive tightness, should be corrected by adjusting helmet pad locations as
instructed in this manual and by ensuring that the appropriate helmet shell size is being used.
All replacement parts should be acquired from Crye Precision or a licensed distributor.

INTRODUCTION
The AirFrame™ ATX is our law enforcement focused ballistic helmet—designed to offer the
same advantages of our original AirFrame™ helmet while meeting IIIA ballistic requirements.
The unique overlapping shell design of the AirFrame™ creates an integrated vent that
provides passive cooling and can reduce the damaging effects of explosive blast waves.
Each AirFrame™ helmet features an Ops-Core®H-Nape Head-Loc™ retention system for
unmatched stability, comfort, and ease of adjustment. Up armoring the AirFrame™ with
ballistic ear or face protection is simple and fast (see our Ears™ and Chops™ for more info).
All helmets and components are compatible with common ear-pro systems like Peltors®and
Sordins®
. Made in the US from US materials.

SHELL SIZING
Follow the instructions below in order to ensure a correct shell size selection. Select the
proper helmet size based on your head circumference. If a measurement falls directly in
between two sizes, select the larger size. See the note at bottom of the page for exceptions.
Whenever possible, try on a helmet and allow the pads to adjust for ve minutes in order to
determine which size has the best t.
MEASURING HEAD CIRCUMFERENCE
Sit straight with your head level. Wrap a vinyl tape measure around your head. Start just
above eyebrow ridges and wrap around widest part of the head as shown in the diagram.
Pull the tape measure tight and record the measurement. Use the table below to determine
the correct helmet size.
NOTE: HEAD SHAPES DIFFER
Users on the threshold of two sizes, but with a narrower head (6” width and below), may be
able to t into the smaller sized shell, where users with a wider head (over 6” width) should
move to the larger size.

*Note: Pads affect sizing—if using an alternative pad set, try on the helmet to choose the proper size.

PAD PLACEMENT
Standard AirFrame™pad placement is shown below. The number of oblong pads varies with helmet size. MEDIUM helmets require 6 oblong
pads, LARGE helmets require 7 oblong pads, and EXTRA LARGE helmets require 8 oblong pads. All helmets require two trapezoidal pads.

Pad placement is designed to offer optimal protection and comfort. It is critical that pads are placed as shown in the below diagrams and that
the pads nearest chinstrap hardware mounting points are situated to overlap said hardware—failure to do so may result in injury or death.

8OPERATOR INSTRUCTIONS
*Straps may need to be retightened after a few minutes of wear as helmet pads can soften.
Don the helmet and ensure that the nape
pad is positioned correctly.
Buckle the chin strap.
Pull the front and rear strap adjusters
until snug.
Ensure the chinstrap is unbuckled and all
straps are loosened.
The nape pad can be tightened by pulling
on the nape adjuster. The nape pad adds
additional stability to the helmet, which
can be useful when wearing NVGs.

FIT ADJUSTMENT
HELMET IS TOO LOOSE OR TOO LOW
If the helmet is too low on the brow, not compatible with eyewear,
or has other similar compatibility issues, it may be too loose.
Increase the number of pads in shell (additional pads can be
purchased separately)
If additional pads do not correct the fit, a smaller helmet shell
size may be required
HELMET IS TOO TIGHT OR TOO HIGH
It is extremely important that the helmet not be sized and tted to sit
too high on the head. If the crown pads do not hit the head (wearer
cannot feel pads), then the helmet may be too high. When tting,
look upward by moving your eyes, but without moving your head. If
the rim of the helmet cannot be seen, the helmet may be too tight.
Try rearranging the pads
If rearranging the pads does not alleviate the tightness, a larger
helmet shell size may be required

CLEANING INSTRUCTIONS
HELMET SHELL
Remove helmet pads from helmet shell and clean separately. Helmet shell can be washed
with a mild soap and water using a soft brush or cloth. Towel dry the helmet shell and
allow to air dry completely indoors or in a shaded area.
HELMET PADS
Helmet pads should be washed by hand using a mild soap and cold water. A soft bristled
brush or wash cloth can be used to remove dirt. Allow pads to air dry indoors or in a
shaded area. DO NOT WRING.
PREVENTIVE MAINTENANCE CHECKLIST
In order to ensure optimal performance, the user should routinely inspect the helmet for
damage, wear marks, or missing components. Any damaged components should be replaced
immediately. Any of the following issues should be immediately reported and remedied:
Shell cracks
Bubbles
Signs of ply separation
Fraying webbing
Damaged plastic hardware
Peeling helmet edging
Loose fasteners
