2 MUSTANG SURVIVAL/ SENTINELTM SERIES – WATER RECSUE DRY SUIT
MSD624 03 - SENTINEL™SERIES WATER RESCUE DRY SUIT (CONT’D)
The Sentinel Series Water Rescue Dry Suit is easily donned/doffed by
the wearer using a diagonal watertight entry zipper across the torso
and wearer’s left shoulder. Customized fit can be achieved through
adjustment of the internal suspenders to modify trunk length for
improved range of motion.
Every Sentinel Series Water Rescue 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 SAR
are inherently dangerous. Users should be aware of risks associated with
these types of operations and complete training in the use of water rescue
operations equipment and techniques.
SENTINEL SERIES SIZING GUIDE
Exclusively available for the Sentinel™Dry Suits, we introduce the

of motion without the expensive custom price tags or long lead times.

INSTRUCTIONS FOR USE
This manual supplies instructional, maintenance and safety
information for the Sentinel Series Water Rescue 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.
NEOPRENE WRIST SEAL FITTING
The neoprene seals should only be trimmed if they are unreasonably
tight and restrict blood flow. The below chart indicates the target
body dimensions for the standard neoprene seals. The seals are
designed to fit the individuals with the smallest measurements. If
your neck and/or wrist is larger than the target dimensions, you will
likely have to trim your seals. If your measurements are better suited
to another size, you can order a Rapid Repair replacement kit in the
appropriate size.

If seal trimming 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 ⅛” at a time. You can always
trim more, but you can’t replace what you have cut off.
Required materials: • Ruler
• Sharp scissors
• White china marker or silver pen
NOTE: ONLY NEOPRENE SEALS CAN BE TRIMMED USINGTHIS PROCEDURE.
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.
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 the seals, have the user don the suit to determine seal
restriction and water-sealing characteristics. Make any additional adjustments
to the seal.

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 (Fig. 3).
3. Thread the end of the nylon strap attached to the suit through the
rectangular clip on the suspenders (Fig. 4).
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
(Fig. 5).
5. Repeat these steps for the other attachment point.
6. Use the suspender strap ends to adjust for a secure, comfortable fit.
