BEFORE YOU BASE, SKYDIVE.
BEFORE YOU GET TOO CRAZY WITH YOUR FREAK 4, TRAIN!
Even our most experienced team pilots need many skydives (10, 20, 30+, perhaps!) before
they feel comfortable and confident in new wingsuit designs. These are people with 10+
years of experience, thousands of skydives, and over 1000 BASE jumps. Please take your
responsible progression seriously: skydive your wingsuit extensively before you BASE jump
it, and train in your wingsuit extensively before you attempt any advanced maneuvers.
The FREAK 4 is designed for experienced wingsuit pilots who want a suit that is capable
of flying an endless variety of maneuvers at any angle. Because the FREAK 4 is capable
of pressurized and stable flight at almost any angle, only your imagination will define the
limits of what is possible in this suit. Please note that the FREAK 4 is a moderate to large
size wingsuit with backfly inlets. What this means is that (like any suit with backfly inlets) the
FREAK 4 will maintain pressure in almost any configuration, even if you are not in control
of it. Respect the limits of your abilities and progress slowly. Seek coaching and qualified
instruction, and always maintain awareness of your surroundings. It is your responsibility to
avoid collisions with other wingsuit pilots, parachutes, all air-traffic, and the planet Earth.
Skydiving and BASE jumping are extremely dangerous, and complacency kills.

USE, CARE, AND FEEDING OF YOUR SQUIRREL
High Aspect Ratio Inlet
The new High Aspect Ratio Inlets on the front side of your
suit require some care. Try not to store your suit in a tightly
packed configuration. Do not store your suit folded tightly in hot
conditions. For instance, don’t leave it crammed into your stash
bag in a hot car for a few hours. In the case of inlet deformation,
massaging them into shape at or above room temperature will
help to reform them.
Air Cross-Section (“Arm Foam”) Options
Your FREAK 4 is shipped with 5mm black foam, which is inserted in the arms. We recommend
starting with this foam option. The FREAK 4 may be jumped without this foam, but your leading
edge will appear less smooth, and be less efficient in flight.
THE ”FREESTYLE” AIRFOIL CROSS-SECTION
The optional “Freestyle” foam is recommended for experienced pilots. It is designed specifically
for the FREAK series. The Freestyle foam improves speed and glide performance, and makes
transitions feel more agile and precise. Adding in this enhanced leading-edge structure will slightly
change the BOC and Riser access. We do not recommend using it for BASE jumping, or in any
situation where a low deployment may occur.

Attaching Your Suit and Gearing Up
For a comprehensive video on how to attach your container to your wingsuit, please watch our
Gearing Up video: http://squirrel.ws/gearingup
Zipper Bungees
The bungees that hold the zippers tight to the main lift webbing (MLW) of your harness must always
be connected. DO NOT jump your suit without the zipper bungees set tightly around your harness
MLW. Securing the bungees on the inside of the MLW usually results in the zippers being closer,
and the hole being smaller.
We highly recommend using a standard pillow handle as the best choice for wingsuit flying. For
more detailed information on the decision of what handle type is best, please see our Reserve
Handle Information PDF here: http://squirrel.ws/handles
NOTE: If you think that the zipper system is not functioning well with your skydive harness (i.e. your
emergency handles are not always 100% accessible), please contact us before your next jump.
You may need to modify the zippers so that the sliders stay locked in place, as per the information
at this URL: http://squirrel.ws/zipperstuff
Keep zippers close against MLW webbing. Handles completely exposed.
Zippers tight against MLW.

Holding Your Prole Gripper, and Positioning the Leading Edge of Your Suit
Holding your grippers correctly is an important part of controlling your FREAK 4. The Integrated
Profile Gripper allows you to pull tension and manipulate the arm wing efficiently, while providing
an aerodynamic inflated “fairing” behind the hand. The top of the gripper is designed to be gently
cradled between thumb and forefinger. It is NOT necessary to hold the gripper itself, tightly.
GOOD: Pilot’s fingers are all on the top surface (back side) of the gripper, resting against the arm wing
end cell. The grip is somewhat relaxed, with the thumb in front and the top of the gripper nestled gently in
the palm of your hand. Note that the gripper itself is not being held tightly.
NOTE:It is NOT necessary to hold the grippers tightly in flight. You can comfortably fly your
suit from exit to deployment with a very light touch on the grippers. It is better to NOT hold
the grippers than it is to hold them wrong, or to hold them too tightly.
Position for belly ight.

The MonoChamber
The Freak 4 is the first public product we have released which uses the MonoChamber design. Air
flows through channels located behind the upper leg area, allowing the arm wings and leg wing to
share pressurization. In addition to smoothing out the leg wing / arm wing junction at the top surface,
the MonoChamber creates a more consistent and coordinated feel in the wing. The most descriptive
word we can use is “homogeneity”. The suit feels more homogenous and compact in maneuvers,
as the wings are no longer separate chambers. Initially concepted purely for drag reduction on high
performance suits, we were pleasantly surprised to feel the significant handling improvement as well.
Arm and Leg Wing Internal Zippers
The FREAK 4’s internal pressure can be fully
customized. For the greatest range and
performance, we recommend flying with zippers
closed. You may experiment with opening them to
reduce internal pressure in the arm and leg wings,
which will make the arm wings feel more supple
and may be to your liking for certain maneuvers.
Make zipper-checks a part of your pre-flight
checklist - zips should be set symmetrically and in
the position you intend, before exit.
Nutsack
Don’t overload your nutsack, it’s made for your
stuff-sack and small / lightweight accessories.
Chest Pocket
The chest pocket can be used as a belly-cam
access zip while also having your phone secured
behind the Velcro strip. Note that it zips open
/ closed from both sides, so always keep your
phone behind the velcro strip in case one or both
of the zippers are left open.

Leg Wing Zipper Pulls
Always fasten your leg wing zipper pulls. If you walk around
with them dragging on the ground, you will ruin them. If your
suit is on, have the zipper pulls connected. Do not drag them
through the dirt.
Hook Knife
Every suit comes standard with an aluminum handle
double-blade hook knife. Check to make sure that the
hook knife is loaded properly and secured.
Sleeping And Bathing Your Squirrel
Don’t smother your Squirrel! When it’s hibernating, it likes to breathe and relax in a cool, dry,
comfortable nest. Do not store your suit for long periods of time in a tightly folded or compressed
manner. Always fully shade-dry your suit if it becomes wet or damp. Gently rinse with fresh water
to clean, or if ever exposed to salt water. Never use chemical detergents – Squirrels like it all
natural, all the time!
Your suit can be hand washed in cold water, or machine
washed cold on a gentle cycle. Never tumble dry your suit.
Hang dry in the shade.
