DESCRIPTION
MSD63X SENTINEL™SERIES – LIGHTWEIGHT BOAT CREW DRY SUITS
MSD64X SENTINEL™SERIES – HEAVY DUTY BOAT CREW DRY SUITS
The Sentinel™ Series Boat Crew Dry Suits are waterproof &
breathable constant wear boat crew dry suits ideal for Law
Enforcement and Search and Rescue (SAR) small boat operations
where crew members don’t intend to enter the water but require
hypothermia protection in case of accidental immersion.
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.
• NEW Mobility Based Sizing™ offers semi-custom size fits without
the custom price tag, reducing bulk and while increasing range of
motion.
• NEW zipper design for entry and relief openings for both male and
female. More comfortable, easier to operate and less maintenance
required than traditional dry zippers
• NEW two-point attachment removable suspender system for an
improved fit, mobility and comfort
• NEW Rapid Repair Technology™ enables users to self-replace neck
and wrist seals and repair small leaks in an hour or less
• NEW 2 Layer design for increased durability (MSD64X Series Only)
• CORDURA®reinforced elbows, knees, seat and wrist and leg over
cuffs
• 5mm neoprene knee pads help prevent injury
• Integrated GORE-TEX®Dry Socks
• Military grade GORE-TEX®BD6.5 waterproof & breathable dry suit
fabric
• Multi-position fleece lined storm collar for improved protection and
comfort
• 2 chest hand warmer pockets (accessible even while wearing a PFD)

2
• 1 calf pocket with neoprene survival hood attachment (survival
hood sold separately)
• 2 arm pockets and 2 thigh cargo pockets
• Large leg and wrist over cuffs have Velcro®closures for adjustability
• 62 square inches of SOLAS retro-reflective tape for increased
visibility
• Duty belt keepers at the waist
• 2 Packages of TIZIP®lubricant
The Sentinel Series Boat Crew Dry Suits are easily donned/doffed
by the wearer using the diagonal entry zippers across the torso and
wearer’s left shoulder and includes relief zippers. Customized fit can
be achieved through adjustment of the internal suspenders to modify
trunk length for improved range of motion.
Every Sentinel Series Boat Crew Dry Suit produced by Mustang is leak
tested to ensure waterproof integrity prior to leaving our factory. All
suits are 100% tested to ensure the highest level of reliability and
performance.
WARNING: Dry suits alone provide inadequate
protection for extreme climate differences. All
users should wear appropriate wicking thermal
undergarments to prevent hypothermia (in cold
climates) and moisture wicking undergarments to
prevent heat stroke (in warm climates).
WARNING: Dry suits are not inherently buoyant.
All users should wear appropriate flotation devices
with the dry suit. Water rescue and maritime law
enforcement are inherently dangerous. Users should be
aware of risks associated with these types of marine
operations and complete training in the use of marine
operations equipment and techniques.

INSTRUCTIONS FOR USE
This manual supplies instructional, maintenance and safety
information for the Sentinel Series Boat Crew Dry Suits.
CCS™ADJUSTABLE NECK SEAL (IF EQUIPPED)
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.

4
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.
RUBBER NECK AND WRIST SEAL FITTING (IF EQUIPPED)
The Rubber Neck Seals and 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. Neck seals shall fit snugly
and remain in direct contact with the neck through all normal head
movements. 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 neck 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.
i) An alternative method is to place the neck seal inside-out, so
the trim rings are facing out, over a large metal coffee 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

5
3. Check for fit and if necessary repeat steps 1 & 2 until there is a
proper fit.
4. Trim wrist seals in same manner as neck seals using very sharp
scissors.
i) 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).
5. After trimming seals, have the user don the suit to determine seal
restriction and water-sealing characteristics. Make any additional
adjustments to the seal.
NEOPRENE NECK AND WRIST SEAL FITTING (IF EQUIPPED)
The neoprene seals should only be trimmed if they are uncomfortably
tight and 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 1/8” at
a time. You can always trim more, but you can’t replace
what you have cut off.
Required materials: Ruler, sharp scissors and a white china marker or
silver pen.
1. Trim only 1/8” at a time. Using a ruler mark a circular line around
the seal that is offset from the edge of the cuff end by 1/8”.
2. Using sharp scissors carefully cut the cuff end at the marked line.
Evaluate the fit and repeat step 1 & 2 until there is a proper fit.

Figure 2
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. 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 rescuer 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.

INTEGRATING THE TWO LAYERS (MSD64X SERIES ONLY)
Your Sentinel Series Heavy Duty Boat Crew Dry Suit is comprised of
two distinct layers: an inner immersion layer and an outer shell. The
inner immersion layer, or dry suit layer, should be treated with care
as this is the layer that provides the water tight protection in case of
water entry. The outer shell layer is fitted with the abrasion protection,
pockets and other external features of the suit. The instructions below
indicate how to integrate these two layers to prepare the suit for use.
1. Completely unzip the entry zipper of the outer shell.
2. Slide the inner immersion layer into the outer shell. Pay attention
that the front of the immersion layer is facing the front of the
outer shell.
3. Align the positions of the duty belt keepers on the inner
immersion layer with the corresponding button holes on the outer
shell.
4. Slide the duty belt keepers through the button holes of the outer
shell.
5. Align the velcro of the outer suit with the velcro of the inner suit
in the three locations along the entry zipper.

Figure 6
Figure 7
6. Ensure that the sleeves of the inner immersion layer are not
twisted inside the suit.
7. The two layers are now integrated and the suit is ready for use.
DONNING THE 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 both the outer shell entry zipper (MSD64X Series Only)
and the waterproof entry zipper are fully opened.
4. Ensure the suspenders are pulled out of the suit legs.
Donning the Dry 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 talcum 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. If you need to pull on the suit to get your hand
through the seal pull on the suit cuff and not the seal. Pulling on
the seal can lead to damage.
6. Roll the Velcro®wrist covers back and refasten to a snug fit.
7. Repeat steps 4 - 8 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. Both sides of the zipper chain should remain
parallel while closing to avoid zipper damage.
CAUTION: Placing undue force on the zipper may
damage the seal and harm the integrity of the suit.
Never forcefully yank on the zipper.

10
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. (MSD64X Series Only) Close the outer shell 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.
12. Tighten the ankle Velcro®covers to a snug fit.
13. 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.
Doffing the Dry Suit
1. Remove all equipment worn over the suit.
2. Thoroughly rinse down the exterior of the suit while wearing it,
paying special attention to the seals and zippers. Remove all dirt,
salt and debris.
3. Loosen Velcro®waist and ankle adjustment tabs.
4. Completely open the outer shell entry zipper and the inner
immersion layer waterproof zipper. If not completely open, the
zippers face the risk of being damaged during doffing.
CAUTION: Placing undue force on the zipper may
damage the seal and harm the integrity of the suit.
Never forcefully yank on the zipper.
5. Insert fingers between neck seal and neck. Gently stretch the seal
outward and upward while pulling neck seal over your head.
6. Remove hands from wrist seals by holding onto the cuff or pull
tab. Point your fingers straight, tucking the thumb underneath the
seal. Slowly pull your hand through the wrist seal. Do not make a
fist when putting your wrist through the seal or pull on the seal.

11
Once your hands are out the seals may be inverted gentle push or
pull the seals so they oriented away from the suit.
CAUTION: Pulling on the wrist seal may damage the
seal.
NOTE: If wearing suspenders, remove suspenders prior
to proceeding
7. Pull suit down past hips and slide legs from the suit.
8. Follow the cleaning and storage instructions for the suit.
CLEANING AND MAINTENANCE
CLEANING
1. Thoroughly rinse your dry suit after every use.
CAUTION: Do not dry clean. Do not iron. Do not
bleach.
2. Treat stains with a pre-wash treatment such as Shout®or
Spray ‘n Wash®. Follow the manufacturer’s instructions. Rinse well.
3. Machine wash warm (104° F/40° C) on gentle cycle using a gentle
powder or liquid detergent. Do not use fabric softener, bleach or
wash-in treatments, as they can affect the suit’s breathability.
CAUTION: Use only a front loading washing machine
or a top loading washing machine that does not have
an adjitator post. Washing machines with adjitator
posts can damage the suit.
4. Tumble-dry using an air setting.
MAINTENANCE
Regular zipper maintenance is recommended to maintain a water-tight
seal, inhibit corrosion and keep the zipper gliding freely. These steps
are essential to zipper longevity:
1. Clean the zipper of any heavy deposits of mud, sand, salt or
foreign substances using warm soapy water.
2. TIZIP®MasterSeal zippers need to be lubricated on the docking
end from time to time. Two packages of TIZIP®lubricant are
included with your suit. Please use the original TIZIP®lubricant or
other available zipper lubricant as listed on following page.

12
3. Carefully apply over the docking end surfaces on front and back
and inside where they connect to the zipper chain.
Figure 9
CAUTION: TIZIP®MasterSeal zippers do not require
the zipper chain to be lubricated, only the docking end.
Lubricating the zipper chain may affect the zippers
performance and is not recommended.
4. Repeat before long term storage leaving the slider closed and
whenever the area is dry during use.
