These neoprene wetsuits are central to the diving gear for many divers. The choice between a wetsuit and a semi-dry suit will primarily depend on the water temperature, the duration of your dive, and your personal sensitivity to cold. Our stock offers you numerous options.

What is a Wetsuit and How Does It Work?

The wetsuit is the most common and versatile option. Its principle is simple: it allows a thin layer of water to infiltrate between the diver's skin and the neoprene. This water is then quickly warmed by your body heat, creating an insulating thermal barrier.

Why is it "Wet"?

Because water circulates within it. For effective thermal protection, a precise fit is necessary: if the suit is too loose, cold water will constantly circulate, nullifying the warming effect and potentially making you cold.

Common Materials and Thicknesses:

Wetsuits are primarily made from flexible neoprene. Their thickness ranges from 1 mm to 7 mm. 3mm wetsuits are common for warm waters, while 5mm wetsuits and 7mm wetsuits are intended for temperate to cold waters.

Advantages for the Diver:

  • Flexibility and Freedom of Movement: The soft neoprene offers great freedom of movement, ideal for recreational dives, snorkeling, or other water sports.

  • Ease of Donning: Generally easier to put on and take off. This is a much-appreciated comfort.

  • Versatility: Suitable for a wide range of water temperatures, from 20°C and above.

  • Cost: Often more affordable than semi-dry or dry suit models.

When Does a Wetsuit Show Its Limits?

It is less insulating in cold waters or during very long dives because water circulates within it.

What is a Semi-Dry Suit and What More Does It Offer?

The semi-dry suit is an excellent choice for divers seeking more warmth than a wetsuit, without the constraints of a dry suit. It is designed to minimize water circulation.

How Does It Work? Will You Stay Dry?

It uses the same principle as a wetsuit but with key improvements. Thicker and snug-fitting wetsuit seals at the wrists and ankles, as well as a specific back zipper (often with an internal flap), significantly limit water entry and circulation. No, you won't be completely dry, but the water that does enter remains trapped and heated by your body, offering superior thermal insulation.

Materials and Distinctive Features:

Semi-dry models are generally made from thicker neoprene than wetsuits (often 5 mm to 7 mm). The neoprene used can be Elaskin neoprene for increased flexibility. Zippers are often made semi-dry by adding neoprene or, for some brands, by using 100% waterproof zippers (like those used on dry suits). The bonding of neoprene pieces is often reinforced with extra glue on the seams to prevent water passage. Systems like Seac Sub's Spacedry can be integrated for better internal comfort.

Advantages for the Diver:

  • Superior Warmth: Offers significantly better thermal protection than a wetsuit by minimizing water entry.

  • Increased Comfort: The diver stays drier and warmer during the dive, including for longer durations or consecutive dives.

  • Versatility: Ideal for temperate to cooler waters (between 10°C and 20°C), allowing for an extended diving season.

Is It Harder to Put On?

Yes, donning can be a bit more difficult than for a wetsuit due to the thickness and snug seals. Sometimes, a little help is needed.

Choosing Your Suit: Which Suit for Which Temperature and Diving Style?

The choice of your suit will depend on the water temperature and your personal comfort.

Choosing Your Suit: Fit, Style, and Comfort

A proper fit is key to your comfort and the effectiveness of thermal protection.

How to Know if the Size is Right?

A suit should be snug, like a second skin, without being too tight. If it's too big, cold water will circulate, canceling out the insulation. If it's too small, it will restrict your movements. Sizes can vary from one brand to another (Beuchat sizing is different from Scubapro). Consult our specific size guides. Donning should be easy. Men's and women's wetsuits are cut to fit each body shape.

Zippers and Seams: Their Role in Watertightness

The zipper is important for watertightness and ease of donning. Glued and blind-stitched (GBS) or liquid-sealed seams are preferable to flatlock seams for better insulation and to limit water entry. The zipper must be reliable.
