SIZING GUIDE
FAST helmets have been designed from the ground up to t the largest group of users in helmet
sizes that most closely match their heads. However, there is still a small percentage of users that
will not t our standard sizing congurations. Please use the sizing guide below to determine your
helmet size and your chinstrap size. If you require a non-standard chinstrap/helmet conguration,
custom solutions are available.

PRO SETUP
FAST Helmets were designed for professionals who expect the most from their equipment. Just like
fine-tuning the suspension on a racecar or sighting in a fire-arm, the helmet must be set up properly
before use to function correctly. If you do not follow these instructions, your helmet will not function
in accordance with stated performance.
ADJUST THE TOP PADS
• Put the helmet on. ½” pads come pre-installed
in the helmet. Turn the dial to loosen the fitband
so that all of the helmet weight is resting on top
of your head.
• With the fitband loose, check how high / low the
helmet is sitting. Forehead pad should be above and
not resting on the bony ridge of your eyebrows.
HEIGHT ADJUSTMENT
• The distance from the top of the eyebrow to the bottom of the
0.5”-1”
fitband should be approximately 0.5”- 1”. There should also be
enough room around your ears for COMMs / hearing protection.
• If the helmet sits too low on your head, remove the ½” top pads
and install the ¾” top pads.
• If the helmet sits at an uncomfortable angle, adjust the top pads,
or use a combination of ½” and ¾” top pads until it sits correctly.
ADJUST THE REAR PADS
• Install the ¾” rear pad. Put the helmet on.
• If you feel uncomfortable pressure on your forehead,
take the ¾” pad out and put in the ½”pad.
• If it feels the same as with the ½” pad (can’t notice
the difference) then keep the ¾” installed. This will
make the helmet more stable and comfortable.
6
ADJUST FITBAND HEIGHT
• Put the helmet on and turn the dial to tighten
the fitband until it feels secure. Look up at the
sky. If the dial digs into your neck, it is too low.
• You can adjust the height of the dial by sliding
the rear fitband liner tabs that attach it to the
inside of the shell up and down.
• Set the dial at the height that is most
comfortable for you.
Page 7
“PRE-LOAD” THE FITBAND
• You can set the shape of the fitband to
match the shape of your head for long
term comfort.
• Push or pull the rear fitband liner tabs
(used for height adjustment in step 3)
to adjust the fitband tension from a
round to more oval shape.
• Hold each rear fitband liner tab with
your hand in the location that sets the
fitband tension in the optimal shape
and then tighten the back screws to lock
the tabs in place.
TIGHTEN BACK SCREWS
• Tighten the back screws to lock the
rear fitband liner tabs, chinstrap and
side rails permanently in place.
• If you don’t do this, all of the
adjustments you just made will slip
and the helmet will likely come apart.
INSTALL THE SIDE PADS
• Install the side pads onto the Velcro patches
on the inside of the helmet. These pads
make the helmet more stable and increase
protection from side impacts.
• If they feel tight or uncomfortable, try to
relocate them into a position that feels good.
Note: Check that all screws
and accessory hardware are
tight and secure.

READY FOR USE!

REPLACEMENT EXTERIOR VELCRO
CAREFULLY REMOVE OLD VELCRO
Note: It may be easier to remove Velcro by heating the helmet
shell to 70oc using a hair dryer. Do not heat helmet above 70oc
or helmet will be seriously damaged.
Using your ngers, carefully peel the Velcro away
from the helmet shell. DO NOT BRISKLY RIP THE VELCRO OFF! Continue this
process by slowly pulling it back until all
Velcro is removed.
CLEAN THE HELMET SHELL
To remove excess adhesive from old Velcro and to ensure
optimal adhesion of new Velcro, gently rub affected areas
with a clean towel and Isopropyl Rubbing Alcohol. Do not
use harsh chemicals. If traces of adhesive remain, you can
use Goo Gone® to remove stubborn residue. Wipe the area
with alcohol again after use. Allow the helmet to dry before
attempting to place new Velcro onto the shell’s surface.

Peel Back
PLACEMENT PREPARATION
Using the diagram to the right, carefully align Velcro
pieces to their proper positions. Test t all pieces before
removing backing. Adhesive on this Velcro is pressure
sensitive. Once in place it needs to be pressed down

REPLACEMENT SHROUD
Before replacing Skeleton Shroud or VAS Shroud, the
helmet’s Fitband and Front EPP Pad must be removed.
Replacement kit includes
(1) Skeleton Shroud, (3)
Screws and (3) T-nuts.
Align the Skeleton Shroud or VAS
Shroud with the existing 3-hole pattern
on the front of your helmet. Insert a
T-nut through the Shroud’s top hole
from the front (outside) of the helmet
shell and use your ngers to loosely
attach a screw from the inside of helmet
shell. Repeat for remaining 2 holes.
BUMPER INSTALLATION
The optional foam backer is included to
stick on the back of the mount arm plate.
This backer can reduce wiggle or vibration
between the shroud, mount arm, and helmet.
Finish by using a screwdriver to tighten
all 3 screws from the inside of shell,
making sure the Shroud is securely
fastened to the helmet.
Note: Tighten screws by hand until
secured. Do not over tighten, this
will cause deformation to helmet
shell and compromise helmet’s
ballistic capabilities.

This helmet provides LIMITED protection for the head and does not offer any protection against neck, spinal, or certain types of
brain injuries including those caused by rotational forces. Some hazards can exceed this helmet’s ability to provide protection and
could cause severe head, brain, or spinal injuries including paralysis or death.
Remember: the higher the impact velocity, the greater the chance of injury / death. Common sense is the best defense.

components are not damaged, cracked, deformed, loose or showing signs of excessive wear. Do not remove or alter the front,
top, or back impact pads. Do not apply paint, solvents, or like products as they could degrade helmet integrity and resulting
performance. Replace your helmet if it is subjected to a signicant impact since the shell and/or liner pads could be damaged
without showing any obvious signs of a problem.
These instructions must be followed by all persons using or maintaining this helmet in order for it to perform as designed. Failure
to do so could result in equipment malfunction, serious injury or death.
