Perform regular preventative maintenance on the suit, valves, zipper and seals.
Inspect the valves, zipper, seals and seams for damage before each dive.
Do not use this drysuit as a main buoyancy device. Always dive with a buoyancy compensator.
This drysuit should always be used with undergarment adapted to the environmental conditions.
Failure to do so could result in thermal hazards such as hypothermia or hyperthermia.
Thermal insulation and buoyancy of the drysuit and undergarments may change at depth.
Always dive with a suit adapted to your size.
Fabric, compounds and additives of the suits might cause allergic reactions to some people.
Failure to follow all warnings and instructions in the manual may result in serious injury or death.

3. DRYSUIT SPECIFICATIONS
NEOPRENE
Neoprene used for drysuit is a closed-cell neoprene foam made of synthetic rubber containing
small enclosed bubbles of nitrogen gas. Nitrogen having a low thermal conductivity, it minimizes
heat transport through the material. Therefore, neoprene material has its inherent thermal protection
and buoyancy. The hyper-compressed neoprene used on SF Tech drysuits is very dense and resists
compression at depth. The suit only loses a small percentage of its surface buoyancy and thermal
insulation when the ambient pressure increases. Overall, a neoprene suit requires less added
insulation under the suit than a trilaminate drysuit.
Our neoprene suits are made of 2mm hyper compressed neoprene, laminated with nylon and
polyesterjersey.Theexteriorlayerismadeofheavy-dutyweavereinforcedwithKevlar®fabricto
withstand wear and abrasion while the inside is designed for comfort. Every seams are sewn with a
two thread locking blind-stitch and the inside is sealed with 3-5 layers of urethane sealant.
TRILAMINATE
Trilaminate suits, also known as trilam or membrane suits, are made of a multi-layer material. This
kindofmaterialisnotasstretchyasneoprene,howeveritismoreexibleandprovidesagood
range of motion. Trilaminate has neither inherent thermal protection nor buoyancy. The suit provides
a waterproof shell and the thermal insulation is made by the undergarment.
Our trilaminate suits are made of a middle layer of waterproof butyl laminated between two layers

TNT: TITANIUM NEOPRENE TRILAMINATE
Revolutionary material invented and developed in the premises of SF Tech, TNT is a trilaminate
material using high density neoprene foam as an impermeable layer instead of butyl rubber

4. ZIPPER
SFTechdrysuitareequippedwithametalYKKProseal®Zipper.Thewaterproofzipperprovidesa
watertight fastener for the drysuit. It is a fragile yet essential part of the suit and should be treated
with the utmost care. The larger teeth visible on the outside of the zipper are clamps that secure
the smaller teeth, visible on the inside surface of the zipper. It is these smaller teeth that interlock
andcreatermevenpressureonthepolymerzippertape,creatingtheseal.Theouterteethmust
be lubricated and the overall fastener must be clean and free of dirt. Proper maintenance of the
fastener will ensure a good seal and a long service life.
USAGE
Takingcareofthe zipper is asimplebut necessary tasktoperform. Apply paran aslubricant
beforeeachdive.Applyparanwhenthezipperisopen,andonlyontheoutsideteeth.NEVER use
silicone-based lubricant. Before operating the zipper, ensure it is clean and free of any objects
(sand, mud, etc.) that may result in poor tightness or damage the zipper.
When donning or dong the drysuit, the zipper MUST BE COMPLETELY OPEN.
Donningordong asuitwithazipper partiallyopenwilldamagethesidetapeand
the zipper will break. When opening or closing, always ensure that the pulling direction
is along the line of the metal teeth and that both sides of the zipper are parallel. It is
very important to avoid catching undergarments in the teeth. If the slider should jam when closing,
DO NOT FORCE IT. Pull back the slider, remove the obstruction and slowly attempt to close it
again.Excessiveforcewillbreakthemetalchainanddestroythefastener.Avoidbendingthezipper

STORAGE AND MAINTENANCE
After using the zipper, it should be rinsed with clean fresh water. Any objects (sand, mud, etc.) found
in or outside of the teeth before operating the zipper may result in poor tightness or may damage
the zipper. When the zipper tape starts to fray, carefully burn the strings to avoid them being caught
in the zipper.
Store the zipper in a cool dry place and avoid direct sunlight. Store the zipper COMPLETELY
OPEN, taking care not to bend it. Storage of the zipper in a closed position for a long period will
cause malformation of the sealing areas. Also, storing partially opened will cause zipper bending. If
theseeectsoccur,slightleaksmayresult.Donotplaceanyheavyobjectonthezipper.
Do not dry clean, machine wash or iron.

6. FITTING AND USAGE
PRE-DIVE
Before each dive, make sure the suit is in good working condition.
Check the overall condition of the suit, looking for tear, hitch or hole.
Inspect the seams, making sure none of the threads are broken.
Control the wrist and neck seals. If a seal is cracked, sticky or worn, replace it before diving.
Make sure the inator, dump valve and P-valve are tighten and function properly. Follow the
manufacturer recommendation.
Inspectandcleanthezipper.Applysomeparanontheexteriorteethofthezipper.
Ifnecessary,dustthelatexwristandnecksealwithunperfumedtalcumpowder.
DONNING
Remove all jewelry, watch and necklace as it could tear the seals or damage the suit.
Put the undergarment suitable to the environmental conditions and the type of diving activity.
Ensure the protective zipper and waterproof zipper are COMPLETELY OPEN.Donningordong
a suit with a zipper partially open will damage the side tape and the zipper will break.
Grab the crotch of the suit and fold the upper part of the suit inside out over the legs to about
waist level.
Make sure the suspenders are outside of the legs, correctly attached and not entangled. The
crossover of the suspenders should be in the back of the drysuit.
Step into the suit with one leg, grasp the suit material at calf level and gently ease the foot into
the boot. Pull the suit up your thigh.
Repeat with the other leg.
Grasp the waist of the suit and gently pull it up so that the crotch of the suit is correctly positioned
betweenthelegs.Becarefulnottoputexcessiveforceonthezipperend.
Put the suspenders over the shoulders and adjust the length.
Optional: Connect the P-valve.
Once properly positioned from the chest down, pull the upper part of the suit all the way up to the
chest.

Let go the undergarment when reaching the wrist seal. Gently push your hand through the wrist
seal. Make sure the undergarments are not caught between the seal and the wrist or it will leak.
Pull the shoulder of the suit all the way to the neck.
Repeat with the right arm.

as it may damage it. For a neoprene neck seal, fold it around 4cm toward the inside to have the
smooth surface against the skin.
Optional: Connect the heating system
To close the zipper, grab both side of the zipper at chest level, lift them up, pull forward then down
in order to move the top rubber stop of the zipper closer to the chest.
Grab the slider loop and pull it down in a direction parallel to the zipper chain. Only minimal
amount of force should be required to close the waterproof zipper. Make sure to not catch any
fabric or foreign object in the zipper as it may damage the teeth.
Fold the telescopic torso to avoid any fold on the zipper.
Adjust and clip the crotch strap.
