MUSTANG SURVIVAL / SENTINEL™ SERIES AVIATION DRY SUIT SYSTEM

MSD697 SENTINEL™ SERIES – AVIATION DRY SUIT
The Sentinel™ Series Aviation Dry Suit System is a waterproof,
breathable, FR constant wear dry suit designed with input from select
Army Aviation units as well as USCG Aviation to aid in hypothermia
protection for extended over water missions in colder climates.
The MSD697 is based on the Sentinel Series platform and offers
a great deal of mobility and comfort.
Optimizing fit, comfort and functionality are extremely important,
especially when a poorly fitted suit can impede on a mission’s efficiency
and your safety. Validated by NAVAIR and the SAR Model Manager
Office, Naval Special Warfare, and swift water and ice rescue instructors
and trainers, our Sentinel™ Series is designed to be compatible with all
types of equipment used in these environments.
A thermal performance of the 0.66 CLO is expected when MSL601
and MSD697 are used together with hood and mitts.

MSL601 SENTINEL™ SERIES DRY SUIT LINER
Designed with a combination Polartec® classic 200 fleece and
Polartec® Power Stretch fleece, this dry suit liner provides extra
insulation protection when in cold water and also helps reduce the
thermal burden out of the water. The wicking fabric and thread
transport excess moisture away from the body to evaporate and
diffuse through the outer layers of the dry suit.
Now Includes:
• Polartec® Power Stretch 4-way stretch with a durable, smooth outer
layer that is wind and abrasion resistant, and a soft inner layer that
pulls moisture away from the skin
• Mobility Based Sizing™ reduces bulk while increasing comfort
and range of motion

duty dry suits
Features:
• Full-length fitted legs and sleeves with stretch panels
• Provides warmth while being light weight, highly breathable,
quick drying and durable

designed to optimize the performance of the Sentinel™ Series
lightweight and heavy duty dry suits
NOTE: TO OPTIMIZE THE DRY SUIT AND LINER PERFORMANCE, AS WELL AS
HYPOTHERMIA PROTECTION, ONLY WICKING UNDERGARMENTS SHOULD BE
USED UNDER THE SENTINEL SERIES DRY SUITS & LINERS.

INSTRUCTIONS FOR USE
FITTING DRY SUIT NECK AND WRIST SEALS
This manual supplies instructional, maintenance and safety information
for the Sentinel™ Series Aviation Dry Suit.
CCS™ ADJUSTABLE NECK SEAL
Mustang’s patented Closed Comfort System CCS™ can be worn loose
to provide comfort out of the water and can quickly be drawn tight
to keep the water out. The adjustable seal also provides increased
durability compared to traditional latex seals and allows the suit to be
worn by multiple users without compromising waterproof integrity.
CAUTION: THE CLOSED COMFORT SYSTEM NECK SEAL (CCS™) MUST BE FULLY CLOSED
TO PREVENT WATER INTAKE.
1. The CCS™ neck seal can be worn loose for comfort, but whenever
there is a risk of accidental immersion the neck seal should be
closed enough so that there aren’t any gaps between the neck seal
and the wearer’s neck.
2. To close, pinch the toggle while pulling the elastic drawstring away
from the neck. For maximum effectiveness the neck seal should be
adjusted to be snug, but not uncomfortably tight
3. Once the neck seal has been drawn tight, the Velcro® tabs can be
attached to keep the elastic out of the way.
4. To loosen, insert fingers between the neck and the neck seal while
pinching the toggle. Then gently pull on the neck seal with your
fingers to loosen.
5

RUBBER WRIST SEALS FITTING
The Rubber Wrist Seals may be trimmed at the initial fitting, but the
seals tend to adjust to the wearer after a short period of time. If no
excessive seal restriction exists, and seal fit is acceptable to the user,
the seals should be left as is. Wrist seals shall fit tightly enough to
prevent water entry, but not tight enough to restrict blood flow.
If seal sizing is required, proceed as follows:
CAUTION: TRIM SEALS WITH EXTREME CAUTION. A SMOOTH TRIM LINE IS ESSENTIAL.
EXCESSIVE OR CARELESS TRIMMING COULD RESULT IN LOOSE SEALS THAT LEAK AND
NECESSITATE REPLACEMENT. AVOID NICKING SEAL FABRIC, AS THIS COULD RESULT
IN TEARING THE SEALS WHEN DONNING AND DOFFING, AND ALSO COULD RESULT IN
SKIN IRRITATION. TRIM ONLY 1 RING AT A TIME. YOU CAN ALWAYS TRIM MORE, BUT
YOU CAN’T REPLACE WHAT YOU HAVE CUT OFF.
1. If neck seal trimming is necessary, turn the neck seal inside-out so
you can see the rings running parallel down the gasket around the
circumference of the neck seal.
2. Trimming only one ring at a time carefully cut between the rings
with a very sharp pair of scissors.
a) An alternative method is to place the wrist seal inside-out,
so the trim rings are facing out, over a metal soup can
(10.5 - 15 oz can) and carefully cut between the rings using
a very sharp razor blade (x-acto knife or utility knife style).
NOTE: VISUALLY INSPECT THE TRIMMED EDGE FOR NICKS. IF THE CUT IS NOT SMOOTH
AND STRAIGHT CAREFULLY TRIM OUT ANY NICKS. NICKS CAN CAUSE A TEAR DURING
DONNING AND DOFFING
3. Check for fit and if necessary repeat steps 1 & 2 until there
is a proper fit.
4. After trimming seals, have the user don the suit to determine seal
restriction and water-sealing characteristics. Make any additional
adjustments to the seal.

ATTACHING SUSPENDERS
To attach suspenders please follow the instructions below. The removable
suspenders can be used to improve fit, lower in-water resistance and reduce
fatigue. Suspenders can be adjusted to a comfortable and secure position.
1. Completely unzip the entry zipper.
2. Open the suit so that the two
attachment points are visible.
3. Thread the end of the nylon strap
attached to the suit through the
rectangular clip on the suspenders.
4. Once the nylon strap has been
threaded, flare the sewn folds on
the strap to prevent it from passing
back through the rectangular clip.
5. Repeat these steps for the other
attachment point.
6. Use the suspender strap ends to
adjust for a secure comfortable fit.

DONNING & DOFFING THE DRY SUIT
Before donning the suit, ensure that appropriate undergarments have
been selected for the conditions.
CAUTION: ALWAYS DON THE DRY SUIT ON A CLEAN SURFACE SUCH AS A TOWEL
OR TARP TO AVOID ATTRACTING DEBRIS. PEBBLES, SAND, DIRT AND OTHER DEBRIS
ON THE GROUND CAN CAUSE DAMAGE TO DRY SUIT SOCK AND COMPROMISE THE
SUIT’S INTEGRITY.
CAUTION: USE EXTREME CARE WHEN DONNING THE DRY SUIT. PRIOR TO DONNING,
REMOVE ALL RINGS, WATCHES, EARRINGS, NECKLACES AND EYEGLASSES THAT WILL
CAUSE DAMAGE TO WRIST AND NECK SEALS. FOOTWEAR OTHER THAN SOCKS MUST
NOT BE WORN INSIDE THE DRY SUIT.
SUIT PREPARATION PRIOR TO DONNING
1. Ensure that the Velcro® wrist covers and ankle covers
are unfastened.
2. Ensure waist adjusters are loosened.
3. Ensure that the waterproof entry zipper is fully opened.
4. Ensure the suspenders are pulled out of the suit legs.

DONNING THE SUIT
1 Slide your legs into the suit until your toes reach the end
of the socks.
2 Don the suspenders. Ensure they are crossed in back but
not twisted.
3 Apply dusting powder inside wrist seals.
4 Place the right arm into the right sleeve.
5 Carefully place the right hand into the right cuff by pointing
the fingers straight, tucking the thumb underneath and inserting
the hand through the seal. Do not make a fist when putting your
wrist through the seal.
6 Roll the Velcro® wrist covers back and refasten to a snug fit.
7 Repeat Steps 4 - 6 for the left arm.
8 Bring the upper portion of the suit over your head, aligning the
neck opening with the top of the head. Reach inside the top of
the neck seal with fingers and gently pull the seal outward and
down as you push your head through. Flatten any folds or rolls
of the seal against the skin.
9 Close the waterproof entry zipper. Reach over your left shoulder
with your right hand and grasp the zipper toggle. While holding
the top of the zipper, pull the toggle down until the zipper is
completely fastened.
10 Ensure the waterproof relief zipper is completely closed and
the slider is fully engaged with the zipper stop. Stow the zipper
toggle in the yellow loop located under the zipper cover.
WARNING: FAILURE TO COMPLETELY CLOSE THE WATERPROOF ENTRY ZIPPER
AND THE RELIEF ZIPPER WILL RESULT IN LEAKAGE OF WATER INSIDE THE SUIT
AND REDUCTION OF SURVIVAL TIME WHEN IN THE WATER. HAVE A FELLOW
TEAM MEMBER DOUBLE-CHECK EACH SLIDE FASTENER TO ENSURE THEY ARE
COMPLETELY CLOSED AGAINST THEIR SEALING PLUGS.
11 Ensure the waterproof relief zipper is completely closed and the
slider is fully engaged with the zipper stop.
12 Burp the suit before water entry. Cross arms in front and gently
slide fingers between the neck seal and your neck, squat down
and force excess air through the neck opening.
