The Ultimate Guide: How To Choose A Scuba Diving Wetsuit


Hello, divers and ocean explorers! You're about to embark on a breathtaking journey beneath the sea, exploring vibrant coral reefs, interacting with captivating marine life, or delving into mysterious shipwrecks. But to do this, you'll need to be equipped with the right gear, and one of the most critical pieces is a well-fitted scuba diving wetsuit.

"How to choose a scuba diving wetsuit?" It’s a question that often leaves beginners and even some seasoned divers scratching their heads. Let's deep dive into the essential details and considerations to help you select the perfect wetsuit for your underwater adventures.

How To Choose A Scuba Diving Wetsuit

Understanding Wetsuit Styles

When deciding on a scuba diving wetsuit, it’s vital to understand the different styles available. The type you choose will largely depend on the diving conditions and personal preferences.

  1. Full Wetsuits: Covering the entire body, these are ideal for cold water conditions or longer dives.
  2. Shorties: These cover the torso, upper thighs, and arms, suitable for warm water diving.
  3. Spring Suits: Similar to shorties, but with full-length legs, these provide a bit more warmth.

Decoding Wetsuit Materials

The material of your wetsuit makes a significant difference in comfort and thermal protection. The most common material used is neoprene, which traps a thin layer of water between the suit and your skin, which your body heats, providing insulation.

Selecting the Right Fit

How should a wetsuit fit? As a rule of thumb, your wetsuit should fit snugly without restricting movement. If it's too loose, it may not provide enough insulation. If it's too tight, it could restrict your movement and even cause discomfort.

The Importance of Wetsuit Thickness

Wetsuit thickness is a key factor when choosing a scuba diving wetsuit. The thickness will determine how warm you'll be in the water. As a guide:

  1. 2mm: Ideal for tropical water (above 30°C)
  2. 3mm: Suitable for warm water (20-30°C)
  3. 5-7mm: Designed for cold water (10-20°C)
  4. 7mm+: Best for extremely cold water (below 10°C)

Zippers and Seams: Subtle but Significant

When learning how to choose a scuba diving wetsuit, the zippers and seams might not seem that important, but trust us, they are. The placement and quality of zippers can significantly impact the suit's ease of use and durability.

Seams are equally important as they affect the suit's comfort and warmth. There are three main types: flatlock, blind stitch, and glued and blind-stitched. Each one offers different levels of water resistance and flexibility.

The Price Factor: Is Expensive Always Better?

While it's tempting to equate price with quality, this isn't always the case. It's essential to find a balance between cost and functionality. An expensive wetsuit may have fancy features you never use, while a cheaper option might meet all your needs perfectly.

Care and Maintenance of Your Wetsuit

Once you've learned how to choose a scuba diving wetsuit, it's crucial to learn how to care for it to extend its lifespan. Here are some tips:

  1. Rinse Thoroughly: After each dive, rinse your wetsuit in fresh water to remove salt, chlorine, and other potentially damaging substances.
  2. Dry Properly: Allow your suit to dry out of direct sunlight, as UV rays can damage the material.
  3. Store Correctly: Store your wetsuit on a wide hanger to help maintain its shape. Avoid folding it to prevent creases.

Choosing Wetsuits for Specific Scenarios

Let's now turn our attention to some specific scenarios you might encounter when diving and the best wetsuit choices for each.

Diving in Tropical Waters

When diving in tropical waters, a shorty or spring suit is your best bet. These styles provide enough insulation while giving you the freedom to move easily underwater.

Cold Water Diving

For colder dives, you'll want a full wetsuit with a thickness of at least 5 mm. Some divers prefer to use a semi-dry suit, which has better seals at the neck, wrists, and ankles to keep cold water out.

Deep Diving

For deep diving, you may want a thicker suit or even a dry suit, which provides the best thermal protection. Also, consider a hooded vest for additional warmth.

Wreck and Cave Diving

For wreck or cave diving, durability is key. Look for a wetsuit with reinforced knees and elbows to withstand rough surfaces.

  1. What thickness wetsuit do I need?

This depends on the water temperature. 2mm is ideal for tropical water, 3mm for warm water, 5-7mm for cold water, and 7mm+ for extremely cold water.


Choosing the right scuba diving wetsuit isn't as intimidating as it may seem at first. By understanding your needs and the various options available, you can find the perfect fit for your underwater adventures. Remember to consider the style, material, fit, thickness, and quality of the zippers and seams. Also, don't forget to take care of your wetsuit post-dive to ensure it lasts for many diving trips to come.
