Choosing the Right Thickness and Size

When choosing the right thickness and size for your wetsuit, consider factors such as water temperature and personal preference.

1-2mm Shorty Wetsuit

A 1-2mm shorty wetsuit is great for warm water. It covers the body’s core but not your arms or legs. This suit lets you move free and easy. People like it because it keeps them cool under the sun.

You can wear a 1-2mm shorty wetsuit in warm weather spots. It protects your skin from getting hurt by the surfboard or sea life too.

3/2mm Full Wetsuit

A 3/2mm full wetsuit is a popular option for surfers in moderate water temperatures. The “3/2mm” refers to the thickness of the neoprene material used in different parts of the wetsuit.

The 3mm thickness is typically found in areas that need more flexibility, such as the arms and shoulders, while the 2mm thickness is used for areas that require less mobility, like the chest and back.

This combination allows for a balance between warmth and freedom of movement. A 3/2mm full wetsuit is suitable for surfing in waters around 60-70°F (15-21°C). It provides enough insulation to keep you comfortable without overheating.

4/3mm Full Wetsuit

A 4/3mm full wetsuit is a good option for surfers who want a balance between flexibility and warmth. The thickness of the neoprene material provides insulation in colder water temperatures, while still allowing for freedom of movement.

It’s suitable for spring or fall surfing when the water is not too cold but still requires some protection. The wetsuit features 4mm thick neoprene on the torso and 3mm on the arms and legs, providing extra warmth where it’s needed most.

With taped seams to prevent water from seeping in, a 4/3mm full wetsuit will keep you comfortable during your surf sessions without restricting your performance. It’s important to choose the right size based on your measurements to ensure a proper fit that maximizes comfort and allows for easy movement in the water.

5/4 or 5/3mm Full Wetsuit

A 5/4 or 5/3mm full wetsuit is a great choice for colder water conditions. The numbers refer to the thickness of the neoprene material used in different parts of the wetsuit. The thicker 5mm neoprene is typically found in areas like the torso and legs, providing extra insulation and warmth in cold water.

The slightly thinner 4 or 3mm neoprene is usually used on areas that require more flexibility, such as the arms and shoulders. This combination allows for both warmth and mobility while surfing or diving in chilly waters.

So if you’re looking to stay comfortable and protected during your cold-water adventures, a 5/4 or 5/3mm full wetsuit would be a great investment.

6/5mm Full Wetsuit

A 6/5mm full wetsuit is a thicker option for colder water temperatures. It provides more insulation and warmth compared to thinner suits. This wetsuit is designed with 6mm neoprene in the torso area and 5mm neoprene in the arms and legs.

It offers excellent protection against cold water, making it ideal for surfing or diving in chilly conditions. The thicker material helps to trap body heat while keeping you comfortable and allowing for freedom of movement.

Choosing a 6/5mm full wetsuit will ensure that you stay warm during your water activities in colder climates or seasons.

Deciding on the Entry System

When choosing a wetsuit, it’s important to consider the entry system that will best suit your needs.

Back Zip

The back zip entry system is a popular choice for wetsuits. It features a zipper running vertically down the center of the back, making it easy to put on and take off. The back zip design provides a good seal against water entry, keeping you warm during your surf sessions.

It’s important to ensure that the zipper is secure and doesn’t allow any water to seep through. Back zip wetsuits are versatile and suitable for various water sports activities like surfing, snorkeling, and scuba diving.

They offer a comfortable fit that allows for freedom of movement in the water.

Chest Zip

The chest zip is a popular entry system for wetsuits. It features a zipper that runs across the chest, providing a more secure and comfortable fit compared to back zips. The chest zip design eliminates water entry while offering better flexibility and freedom of movement.

This type of entry system is commonly found in high-performance wetsuits, perfect for surfing or any water sports where agility is key. The chest zip also keeps your back free from excess material, reducing bulkiness and improving comfort during extended periods in the water.


Zipperless or zip-free wetsuits are designed without a traditional zipper closure system. Instead, they use alternative methods to keep the wetsuit snug and secure. These types of wetsuits provide a more flexible and streamlined fit, allowing for better freedom of movement in the water.

Zipperless wetsuits also minimize water entry through the suit, keeping you warmer during your surf sessions. They are typically sealed with glue or liquid tape to ensure maximum durability and prevent water from seeping in.

Some popular brands offer zipperless options with innovative entry systems like chest zips or magnetic closures that make them even easier to put on and take off. When choosing a zipperless wetsuit, consider factors such as thickness, seam construction, lining material, and overall comfort to find the best option for your needs.

Selecting the Right Seams

Choose from different types of seams for your wetsuit, such as flatlock, blindstitch, taped, and sealed.


Flatlock is a type of seam used in wetsuits. It is created by overlapping two pieces of neoprene and stitching them together, resulting in a flat, visible seam. Flatlock seams are not fully sealed, which means they may allow some water to enter the wetsuit.

However, they are more comfortable and flexible compared to other types of seams. Flatlock seams are commonly found in wetsuits designed for warmer water temperatures or activities where flexibility is key, such as surfing or paddleboarding in milder conditions.

They are an excellent choice if you prioritize comfort and freedom of movement over maximum insulation.


Blindstitch is a type of seam used in wetsuits that helps to minimize water entry and increase durability. It involves stitching the neoprene panels together without penetrating all the way through, creating a watertight seal.

This makes blindstitched seams great for colder water conditions as they provide more insulation and keep you warmer. They also offer better flexibility due to their flat construction.

So if you’re looking for a wetsuit that can keep you comfortable and protected in chilly waters, choosing one with blindstitched seams is a smart choice.


Taped seams are an important feature to consider when choosing a wetsuit. These seams are sealed with waterproof tape, which helps to prevent water from entering the suit and keep you warm while surfing or diving in colder waters.

Taped seams offer excellent durability and can prolong the life of your wetsuit by preventing seam damage and wear. They also provide added comfort and flexibility, allowing for unrestricted movement in the water.

When selecting a wetsuit, look for taped seams to ensure maximum protection and comfort during your water activities.


Sealed seams are an important consideration when choosing a wetsuit. They help to keep water out, keeping you warm and comfortable in the water. Sealed seams use a combination of glue and stitching to create a watertight seal that prevents water from seeping through the seams.

This is particularly important for surfers who spend long hours in the cold ocean waves, as even a small amount of water can make you feel chilly and affect your performance. Some popular types of sealed seams include blindstitch and taped seams, both of which provide excellent protection against water infiltration.

When selecting your wetsuit, be sure to check if it has sealed seams for maximum warmth and insulation.
