Dry suit diving: what it is, advantages and why choose it

Dry suit diving is an increasingly popular activity among divers who want to extend their diving season and explore cold waters in greater comfort. Unlike a wetsuit, a dry suit keeps the body completely isolated from the water, allowing for better thermal control and a more comfortable underwater experience.

Thanks to its watertight design, the dry suit has become an ideal choice for both recreational divers and those who engage in technical or extended dives.

What is a dry suit and how does it work?

A dry suit is diving equipment designed to prevent water from coming into contact with the diver's body. To do this, it has seals around the neck and wrists, as well as a watertight zip. Air is introduced into the suit through a valve connected by a hose to the regulator on the cylinder, which helps to maintain thermal insulation and contributes to buoyancy control. The air can be purged through another drain valve located on one of the arms. Si-tech brand valves are the most prominent.

Unlike a wetsuit, insulation does not depend on trapped water, but on thermal underwear and the design of the suit itself.

Advantages of diving with a dry suit

• Diving with a dry suit offers multiple benefits, especially in demanding environments:
• Greater thermal protection in cold water
• Possibility of longer dives
• Better buoyancy control
• Greater comfort before and after the dive
• Access to new destinations and diving conditions

These advantages make the dry suit an excellent investment for those who want to dive all year round.

Types of dry suits for diving

There are mainly two types of dry suits, each with specific characteristics:

Neoprene dry suits

Neoprene dry suits offer thermal insulation thanks to the material they are made of. They tend to have a tighter fit, which reduces the volume of air inside and facilitates a more hydrodynamic position underwater. They are a highly valued option for divers who seek simplicity and warmth without relying so much on undergarments.

Tri-laminate dry suits

Tri-laminate suits are notable for their lightness, durability and quick drying. They do not provide thermal insulation on their own, but allow different inner layers to be used depending on the water temperature. This versatility makes them an ideal choice for divers who dive in different weather conditions.

Essential accessories for dry suits

To get the most out of dry suit diving, it is important to have the right accessories. Dry suit gloves, hoods and thermal undergarments directly influence comfort and dive duration. Keeping your hands and head protected helps conserve body heat and improves the overall experience.

Dry suit maintenance

Proper maintenance of your dry suit is key to extending its life. It is recommended that you rinse it with fresh water after each dive, clean and lubricate the zips regularly, and store it in a cool, dry place away from sunlight. These basic care tips will ensure optimal performance for years to come.

Is it worth diving with a dry suit?

For many divers, the answer is clear: yes. A dry suit not only increases comfort, but also expands diving possibilities and improves safety in cold conditions. It is a natural evolution for those who want to continue exploring the underwater world without temperature being a limiting factor.

Is it necessary to take a specific dry suit course?

Yes, to dive with a dry suit, you need to be trained in the use of the dry suit in order to dive safely.
