INTRODUCTION
The AirFrame™ ballistic helmet sets new standards in protection, comfort, and modularity.
Complete AirFrame™ helmets weigh less than complete ACH 2002 helmets while providing
more coverage area. The AirFrame™ was developed with a mandate to dramatically reduce
headborne weight while exceeding common frag threats. A complete medium AirFrame™
helmet weighs only 2.30 lbs., and the large weighs a mere 2.55 lbs. 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 OpsCore®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. All helmets and components are compatible with common ear
pro systems like PELTORS®and SORDINS®. Made in the US from US materials.
FEATURES
Revolutionary vented shell design for passive cooling
Covers more of wearer’s nape than traditional designs
Modular ear and face protection available
Modular ARC-Rail™ system available (O² compatible)
Contain 3/4” pads
Can be pre-drilled at factory for 3-hole or 4-hole NVG mounts (conguration compatible
with OpsCore®and Wilcox®3-hole mounts)

SHELL SIZING
Follow the instructions below in order to ensure a correct shell size selection. Select helmet
size based on head circumference. If a measurement falls directly between two sizes, select
the larger size. See note at bottom of page for exceptions. When possible, try on an actual
helmet and let pads adjust for ve minutes to choose size that ts best.
*Note: Pads affect sizing—if using an alternative pad set, try helmet on to choose best size.
MEASURING HEAD CIRCUMFERENCE
Sit straight with 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.

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.

6OPERATOR INSTRUCTIONS
*Straps may need to be retightened after a few minutes of wear as helmet pads can soften.
Don helmet and ensure that nape pad is
positioned correctly.
Buckle chin strap.
Pull the front and rear strap adjusters
until snug.
Ensure chinstrap is unbuckled and all
straps are loosened.
The nape pad can be tightened by pulling
on 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 helmet is too low on brow, helmet is 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 fit, a smaller helmet shell 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 crown pads do not hit head (wearer
cannot feel pads), then helmet may be too high. When tting, look
upward by moving eyes, but without moving head. If rim of helmet
cannot be seen, helmet may be too tight.
Try rearranging pads
If rearranging the pads does not alleviate the tightness, a larger
helmet shell 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
