Dry suit diving is
Depending on the innerwear, the change can be surprising.
Introducing innerwear for diving
There are also innerwear made specifically for dry suits, designed to be used under high pressure and in the enclosed space of a dry suit. Here we will introduce the innerwear actually used by Current Blue instructors and dive masters in the waters of Izu and Boso. As they are specially designed, they are highly recommended as they can efficiently keep you warm with little buoyancy.
Base Layer
[Outlast]
This base layer adjusts between hot and cold and maintains an ideal body temperature. By using different mid-layers according to the season, it can be used for a wide range of periods and areas, with water temperatures ranging from -2°C to 22°C. It also minimizes sweating during land work, making continuous diving comfortable. It is a recommended base layer for those who dive frequently, as it is warmer and more durable than simple quick-drying base layers. It is a base layer that is popular among Current Blue instructors, dive masters, and veteran divers.
Outlast, developed for NASA, is a cutting-edge temperature-regulating material that keeps you comfortable whether it's hot or cold. Whether it's a scorching hot day or a bitterly cold place, it works to maintain the temperature that humans find most comfortable (31°C to 33°C). It works directly on the surface temperature of the human skin, not on the outside temperature or the body's internal temperature, to create an ideal comfortable environment that is neither too hot nor too cold.*Click here for an introduction to Outlast .
Mid Layer
[Thermal Body Smoother]
A mid-layer made by World Dive. This is an innerwear for dry suits, made of fabric with excellent breathability, water repellency, heat retention, and stretchability. The surface repels moisture and keeps out the wind, while allowing moisture from the skin surface to escape. In addition, the surface is treated to allow for smooth putting on and taking off, and the design emphasizes soft comfort and functionality, allowing for both ease of movement and comfort. The pullover has a front zipper for smooth putting on and taking off, and the trousers are set high at the waist to prevent the back from being exposed when sitting down. It is made to be slightly loose.
The material "ZAMZA" used in the Thermal Body Smoother combines material properties and lamination to achieve high pressure resistance, high moisture permeability, and low condensation. It converts sweat into water vapor and releases it, so you can stay comfortable and warm even when you sweat. In addition, the surface is highly water-repellent, so even if water gets inside the dry suit, the surface of the inner layer will repel it. The fabric is easy to wear and can withstand water pressure, and the high-density knit is flexible and stretchy, allowing it to follow any movement without stress. It is a high-performance material.
Mid Layer
[Comfort Prime]
A mid-layer for low water temperatures made by Mobies. This is the ultimate mid-layer that turns the harsh winter into midsummer, using PRIMALOFT, which is also used for mountain climbing. It is the ultimate in warmth. In addition, it is an inner layer that is lightweight, highly water-repellent, and super dry. It also has diver-friendly details such as ventilators on both upper arms (to make it easier to exhaust dead air inside the inner layer) and foot cords (to prevent the hem from rolling up). It can be used for a wide range of activities, from the Izu and Boso seas in the middle of winter to drift ice diving at -2°C. It is best to wear Outlast as a base layer.
PrimaLoft® is an innovative ultra-fine microfiber material developed by ALBANY at the request of the US military as a substitute for down. PrimaLoft® is not only light and warm like down, but also flexible, and has water repellency that down does not have. It was born as an innovative artificial down that combines unprecedented functionality (thermal insulation and cold protection technology) with high practicality that can be used in any environment.
Support Items
[Winter Gloves]
These gloves are made of thick fabric to minimize water ingress and egress. They are a must-have item for the winter season. The area above the wrist, where body heat is released the most, is warmed with 3.5mm neoprene rubber to keep heat in. The neoprene rubber does not let wind through, so your hands won't get numb from the wind even after exiting the boat.
Support Items
[Diving Food]
This is a hood made for diving, made of custom-made brushed material. The neck area is made of high-stretch jersey to reduce pressure, and the area that touches the face is made of skin material to minimize water ingress and egress. The brushed material hood has excellent heat retention, making it a must-have for diving in water temperatures below 20°C.
Support Items
[Elfit Plus]
These socks are made from the finest Merino wool and are made especially for diving. They are a must-have for the winter season. They fit your bare feet well and won't slip when you kick with your fins. They won't leave you feeling wet and won't make you cold from sweat. They also have antibacterial and deodorizing properties unique to wool, so you don't have to worry about unpleasant odors. They are the perfect item for the muggy winter season. Keeping your feet perfectly warm will make your diving experience even more comfortable.
Support Items
[Boat Court]
This is a hooded outerwear made of chloroprene rubber specifically for diving. It is water and wind proof and is very useful for intervals at the beach. Even if you get seawater on it, you can just rinse it with water in the shower like you would wash a suit. This is an outerwear unique to divers and a must-have item for winter diving.
Support Items
[Cold weather accessories]
It is also very important to keep warm during surface intervals. When diving, you may not always be able to rest in a heated room. Therefore, it is important to keep warm during intervals. A neck warmer, knitted hat, and gloves are essential items. Current Blue lends out these cold weather accessories free of charge, so please feel free to use them.
He who controls the inner world controls the sea!
By dressing properly for the cold, you can enjoy safe and comfortable diving!
