XV-4 Drysuit

Much has been written over the years about SEASOFTs incredibly comfortable, technologically advanced drysuit, the SEASOFT XV-4 said this:

The SEASOFT XV-4 is the perfect instructors suit when you want to be warm and comfortable and will be in your suit for hours. It is also perfect for that new diver who simply wants to experience the underwater world in absolute comfort, warmth and efficiency.

Here is what one of our customers said

The SEASOFT XV-4 is a new type of fabric-coated neoprene similar to the swimwear used by Olympic swimmers. It has an exterior weave of tightly woven nylon threads that makes it very abrasion resistant with very little hydro drag. The SEASOFT XV-4s technologically advanced exterior dries very quickly and it has an incredible amount of stretch. This neoprene is semi-compressed and is rated to 180 feet (55 meters) in water temperatures of 55F to 75F. It is assisted in staying this warm due to the use of two layers of SEASOFTs TITANIUM FLAKE FOIL. Below 55F a diver will want to use the ALASKA Undergarment.

The SEASOFT XV-4 is truly a drysuit for any diver to covet, enjoy, and dive year after year.

The SEASOFT XV-4 also has:

– SEASOFTs world famous built in STEALTH Boots with an elevated heel and arch supports. if you are going to carry a hundred pounds of gear or more, you should have the footwear to do so.

– STRETCHTEX 3.5 mm neck and wrist seals that are warm, comfortable, durable and dry! They fold under so that the air in the fold, in an effort to “escape”, presses the inner layer against your skin creating a watertight seal.

– Forearm mounted exhaust valves dump air 5 X faster than shoulder mounted exhaust valves. When the air is expanding in the drysuit during an UNINTENDED ASCENT and you are dumping air, there are times with a shoulder dump that you are dumping air only as fast or not even as fast as the air is expanding as you rise (Boyle’s Law). BUT with a forearm mounted exhaust valve you are able to dump ALL of the air in the suit in a second or two – thus protecting you from an unintended, possibly dangerous ascent.

How does it dump air so quickly? There are a couple of factors in play. The XV-4 has a Raglan sleeve design, the sleeves are wide where they are attached to the torso. This allows air to freely move to the exhaust valve when the arm is raised. This creates a funnel ending at the exhaust valve. So when the diver wants to exhaust air they simply lift their arm as if their arm was their BC deflator hose and the air is funneled to the exhaust valve and it “burst” out until you lower your arm. Most of the time it will be a half second flick of the arm. Of course, because the valves are Si-Tech’s best pressure sensitive, adjustable valves, there is never a need to push a button or even touch the valve. It all takes place with a simple, momentary lift of the forearm. What could be easier, safer or more efficient?

– Kneepads like made of a special abrasion resistant material called SHARKSKIN, this kneepad should last for the life of your drysuit.
