One of the most important elements to practice scuba diving is the wetsuit, but what do you know about them? Do you know, for example, what wetsuits are made of? What materials allow divers to stay comfortable and protected underwater?
In this article, we will tell you everything you need to know about wetsuits, the materials used in their manufacture, their functions and how to choose the most suitable one for each type of dive.
What is a wetsuit?
A wetsuit is a garment designed to protect the diver from cold, friction with marine organisms and loss of body temperature underwater. Its main function is to maintain a barrier between the body and the water, reducing heat transfer and making the dive safer and more comfortable.
Wetsuit: What is it made of and how to choose it?
Wetsuits are designed to provide thermal insulation, buoyancy and protection in underwater environments. Although other materials are also used in their construction, they are primarily made of neoprene. A synthetic material that provides thermal insulation by creating a layer of water between the body and the suit, which is warmed by body heat.
Types of wetsuits
Scuba diving suits come in different types:
- Wet suits: These are the most common and allow the entry of a small amount of water that the body heats to maintain the temperature.
- Material: Neoprene.
- Thickness: Varies according to water temperature (3 mm for warm water, 5-7 mm for cold water).
- Characteristics: They allow the entry of a thin layer of water that is heated by the body.
- Semi-dry suits: They have watertight closures to prevent water from entering easily, providing greater thermal insulation.
- Material: High quality neoprene with reinforcements in key areas.
- Features: Reduce water entry with seals at neck, wrists and ankles.
- Dry suits: Completely waterproof, used in cold waters and combined with thermal underwear.
- Material: Neoprene or synthetic membranes (such as trilaminate).
- Characteristics: They do not allow the entry of water and are used with thermal clothing underneath. Ideal for very cold waters.
What material is the wetsuit made of?
Most wetsuits are made of neoprene, a flexible, insulating synthetic material containing small air bubbles that reduce heat loss in the water.
Common wetsuit materials
- Neoprene: It is the most widely used material in diving suits, as it provides elasticity, thermal insulation and resistance to compression at depth.
- Nylon and Spandex: They are used as an outer coating to improve the suit’s strength and make it easier to put on.
- Titanium or graphite: Some wetsuits include layers of these materials to improve thermal insulation without increasing the thickness of the neoprene.
- Latex or silicone: Present in seals that prevent water from entering the neck and wrists, in drysuits.
What is a wetsuit for?
Scuba suits serve several essential functions for divers:
- Thermal insulation: They reduce body heat loss, allowing longer and safer dives.
- Protection against chafing and cuts: Avoid injuries caused by corals, rocks or marine life.
- Buoyancy: Some wetsuits help maintain neutral buoyancy, making it easier to control the dive.
- Reduced fatigue: They keep the body warmer, which reduces physical exertion during prolonged dives.
How to choose the best wetsuit for diving?
There are different types of wetsuits and of different materials, each one adapted to specific needs according to the water temperature and the diving activity. When choosing the right wetsuit, it is advisable to take into account the following aspects:
- Water temperature:
- Warm waters (25-30°C): 3 mm wet suit.
- Temperate waters (18-25°C): 5 mm wet suit.
- Cold water (<18°C): Semi-dry or dry suit of 7 mm or more.
- Type of closure:
- Back zipper: Easier to put on and take off.
- Front closure: Offers greater comfort and less water entry.
- Fit and size:
- It should be snug, but not restrictive, to prevent excessive water ingress and allow mobility.
- Conditions and type of diving:
- For technical diving or dives in very cold water, a dry suit is recommended.
- In temperate climates, a 5 mm wetsuit may be sufficient.
- For recreational diving, wet suit.
- Quality and durability:
- Look for reinforced seams and water-resistant zippers.
- Comfort and mobility:
- Try on the suit before you buy it to make sure it allows you to move easily.
Choosing the right wetsuit is key to enjoy diving safely and comfortably.
Maintenance and care of a wetsuit
The maintenance and care of a wetsuit is essential to prolong its life and ensure its performance. Here is a practical guide:
- Washing: Wash your wetsuit and rinse it with fresh water after each use. Use mild soap if necessary.
- Drying: Dry inside out, in the shade and in a ventilated place. Avoid direct sun and tumble dryers.
- Storage: Store hanging or spread out, in a cool, dry place. Use wide hangers.
- Repairs: Check for damage and use neoprene patches for small cuts. Take loose seams to a specialist.
- Zippers: Lubricate them with specific wax and rinse them well.
- Avoid chemicals: Avoid exposing your suit to fuels, oils and chemicals.
By following these tips, your wetsuit will maintain its thermal insulation, flexibility and durability, allowing you to enjoy many more dives.
