Wetsuit

If you think all wetsuits are the same, think again.

While you might be familiar with wetsuits from surfing or other water sports, a scuba diving wetsuit is specifically designed to meet the unique demands of diving.

Dive wetsuits are made primarily from neoprene and trap a thin layer of water between your skin and the suit that your body heat warms.

Besides providing essential thermal insulation and protection against the cold, scuba diving wetsuits create some extra buoyancy and shield your skin from scrapes and stings.

Why Wetsuits are Essential for Scuba Diving

Even in tropical waters, you'll usually want a wetsuit, particularly if you're making multiple dives.

Your core temperature can drop over consecutive dives, making you feel chilly even in warm water.

Thermal protection: Water conducts heat away from your body 20 times faster than air. A wetsuit helps maintain your body temperature, preventing hypothermia even in warmer waters.

Buoyancy: Wetsuits provide some buoyancy, which can help with your overall buoyancy control underwater.

Protection: They shield your skin from scratches, stings, and abrasions from marine life or underwater structures.

Sun protection: Wetsuits offer UV protection when you're at the surface between dives.

Types of Scuba Diving Wetsuits

Full Wetsuit

Full wetsuits cover your entire body from neck to ankles and wrists.

They're ideal for colder water temperatures and provide maximum insulation and protection.

Full suits come in various thicknesses, typically ranging from 3mm to 7mm, with thicker suits offering more warmth.

Shorty Wetsuit

Shorty wetsuits, also known as "spring suits," have short sleeves and legs, usually ending at the elbows and knees.

They're perfect for warmer waters (75-85°F) and offer core insulation while allowing more freedom of movement.

Shorties are typically 2-3mm thick and are easy to put on and take off.

Farmer John/Jane Wetsuit

Farmer John (or Jane) wetsuits consist of two pieces: a sleeveless long john that covers the torso and legs, worn under a separate jacket.

This style gives you good insulation while allowing more flexibility.

You can adjust your thermal protection by wearing the long john alone or with the jacket.

Farmer John suits are versatile and great for various water temperatures.

Differences Between Scuba and Surfing Wetsuits

Scuba and surfing wetsuits have distinct differences.

These variations aren't just for show - they're designed to meet the specific needs of each activity.

Scuba Wetsuit

Material Composition

Made from denser, compression-resistant neoprene that maintains insulation at depth.

Thickness

Generally thicker (e.g., a 5mm suit) to provide warmth in deeper water.

Design Features

Reinforced areas to withstand wear from dive gear.

Stronger seams and durable materials in high-stress areas.

Often include pockets for dive accessories.

Flexibility

Allow movement but focus more on insulation and durability.

Entry Systems

Made with robust zippers or seals to prevent water entry during prolonged submersion.

Surfing Wetsuit

Material Composition

Use more flexible neoprene with a higher bubble content for better elasticity and movement.

Thickness

Typically thinner (e.g., a 4/3mm suit) as they focus on flexibility over insulation.

Design Features

Knee pads or chest panels for protection against board abrasion.

Simpler entry systems since surfers aren’t fully submerged for long periods.

Flexibility

Prioritize a wide range of motion for paddling and riding waves.

Entry Systems

Often have simpler entry systems suitable for quick in-and-out use.

Wetsuit Thickness and Temperature Guide

Choosing the right wetsuit thickness is critical for your comfort and safety underwater.

Here's a quick guide to help you match wetsuit thickness to water temperature:

80°F (27°C) and above: 1-2mm shorty or full suit
73-79°F (23-26°C): 3mm full suit
66-72°F (19-22°C): 5mm full suit
50-65°F (10-18°C): 7mm full suit or semi-dry suit
Below 50°F (10°C): Drysuit recommended

Of course, your personal tolerance to cold and factors like dive duration and depth can affect your choice.

It's always better to err on the side of warmth if you're not sure which thickness is best.

The last thing you want to do is end your dive early because you're shivering.

Choosing the Right Fit and Material

Fit and Sizing

A properly fitting wetsuit is snug but not restrictive.

To find your size:

Measure your chest, waist, hips, and height.

Compare these measurements to the manufacturer's size chart.

If you're between sizes, choose the smaller size for a snugger fit.

When trying on a wetsuit, make sure there's no loose material or air pockets.

You should be able to move freely, especially around the shoulders and arms.

Material and Construction

Most scuba wetsuits are made from neoprene, a synthetic rubber that provides excellent insulation.

Newer materials like limestone-based neoprene offer improved flexibility and environmental benefits.

Consider these eco-friendly options if they're within your budget.

Sealed seams

Look for glued and blind-stitched seams for better water resistance.

Thermal linings

Some suits have special linings to increase warmth without adding bulk.

Reinforced knees and shoulders

These high-wear areas benefit from extra durability.

Price Ranges for Scuba Diving Wetsuits

Entry-Level

Entry-level wetsuits typically range from $100 to $300.

These are great for beginners or occasional divers.

Features:

-Basic neoprene construction

-Flatlock stitching (less water-resistant but more comfortable)

-Limited thickness options

Mid-Range

Mid-range wetsuits, priced between $300 and $500, offer a good balance of quality and affordability.

Features:

-Better quality neoprene

-Glued and blind-stitched seams

-More thickness options

-Some thermal linings

High-End

High-end wetsuits can cost $500 or more and are the most comfortable and durable.

Features:

-Premium, ultra-flexible neoprene

-Advanced thermal linings

-Customizable fit options

-Reinforced wear points

-Innovative closure systems
