This three layered fabric is composed by nylon-butyl-nylon. Its weight is 400grams per square meter.
It is a very resistant material to make drysuits and yet very comfortable for any type of diving.It’s perfect for drysuits with little to no protections or either drysuits for extreme conditions when combined with Cordura protections, such as technical diving or cave diving (which is the case on the Black Pearl Cave eXtreme dry suit).An important feature of thismaterial is the porosity which allows the glue used during the manufactirung process to anchor perfectly. This offers very long lasting and great reasistance to the Black Pearl drysuit.

 

The valves on the Black Pearl Drysuits are strategically positioned to allow perfect access to the inflation valve in the middle of the chest and to allow the air to be dumped easily and smoothly through the exhaust valve by just lifting the elbow, even when the diver is in a horizontal position.

Black Pearl uses an exclusive system to install the valves on the drysuits. There is a rubber seal which is specially designed for dry suits with overlay protections. It makes it possible to install the inflation and exhaust valves without glues or silicone, on the field. This system makes it easy to clean, replace or fix the valves instantly or even install heating system adapters in a second.

Sitech valves are the default valves on Black Pearl diving drysuits. The reasons are the following:

The button style inflation valve allows perfect control of the amount of air that is injected in the drysuit and it can rotate round and round infinitely.

The sitech exhaust valve has a smaller mushroom valve inside than other exhaust valves which allows the diver to dump air from the drysuit with maximum control. Its smaller size also reduces the risk of leaking caused by vacuum if the suit is not inflated enough during the descent of the dive.

As an option, Apeks valves can be installed on the Black Pearl dysuits. Black Pearl is a brand that installes all its valves, even Apeks, without glues or silicone.

The Apeks inflation valve is also button style like Sitech but the main difference is that it can rotate one round in one sense and then it needs to turn round the other way.

The Apeks exhaust valves have a larger mushroom valve than the Sitech valves which makes dumping air faster but it increases the risk of leaking when under vaccum.

Apeks High profile dump valve:

This valve used to be the preferred by technical or_cave divers because it gives the possibility to service_the valve without the need to unscrew the whole unit off_the suit. With the Black Pearl rubber seal system this is_not necessary anymore but it still is a very requested valve.

Apeks Low profile dump valve

Compared to the high profile dump valve this one is_wider and flatter. The performance is the same because the mushroom valve inside is identical, but it makes it easier to get in_and out of the BCD/harness due to its shape.

Black Pearl Diving Drysuits are all equipped with self front entry zippers. This allows the diver to be autosufficient while dressing up and to have total control over the zipper manipulation. Statistics show that most zippers get damaged by the people who help divers get dressed with non self entry dry suits, so having total control over probably the weakest part of any drysuit is crutial.

There is always a nylon zipper over the main zipper to keep it protected from scratches, sand, or anything that can compromise it.

BDM brass zipper is the default main zipper on the Black Pearl Diving dry suits. This brand is well known to be the best brass zipper manufacturer over the world. If correctly maintained it can last more than 300 dives.

T-ZIP Masterseal PU zippers have been used in the past on Black Pearl drysuits but the reliability of this product is still not clear. Some zippers have lasted as long as the BDM zippers and are so much more comfortable to operate, but unfortunately some units have had very short life without a clear reason or explanation from the manufacturer. So T-ZIP Masterseal PU zippers are only installed by special request but not covered by warranty.
