Wetsuit thickness is measured in millimeters and the first number measures the center of the suit (your core or sternum) or torso and the second number is the thickness of the material around your appendages (arms and legs). So in a 3/2MM wetsuit, the torso of the wetsuit is 3 millimeters thick and the arms and legs are 2 millimeters thick.  The thicker the suit the more warmth it provides but the tradeoff is less flexibility.

An open cell wetsuit and a closed cell wetsuit are two different types of wetsuits that offer varying levels of insulation and comfort. The main difference between them lies in the material used on the interior lining.

1. Open Cell Wetsuit: An open cell wetsuit is designed with a neoprene foam lining that features exposed cells. These cells are directly in contact with the skin when the wetsuit is worn. The open cell lining provides excellent insulation by trapping a thin layer of water against the skin, which is then warmed by body heat. This layer of water creates a barrier that helps maintain warmth. Open cell wetsuits are often used in colder water conditions and when diving down to very cold depths as they provide superior insulation. However, they can be more challenging to put on as the exposed cells can stick to the skin.
2. Closed Cell Wetsuit: A closed cell wetsuit, also known as a lined or sealed wetsuit, has a foam or polyester lining with a smooth, sealed surface. The cells in the foam are sealed, preventing water from entering the wetsuit. Unlike open cell wetsuits, closed cell wetsuits do not rely on a layer of water for insulation. Instead, the foam of polyester  material itself acts as a thermal barrier, trapping a thin layer of air between the suit and the skin. Closed cell wetsuits are typically easier to put on and take off compared to open cell wetsuits. They are commonly used in warmer water conditions or for activities that involve more movement and flexibility, such as surfing or other water sports.

It’s important to note that the choice between open cell and closed cell wetsuits depends on factors such as water temperature, personal preference, and the specific activity being undertaken.

There are several aspects of eco-friendly wetsuits that are important to consider:

1. Sustainable materials: Eco-friendly wetsuits are made from sustainable materials that have a lower impact on the environment than traditional neoprene. These materials may include natural rubber, recycled rubber, or neoprene made from limestone instead of petroleum-based materials.
2. Low-toxicity production: Eco-friendly wetsuits are produced using low-toxicity methods that minimize the use of harmful chemicals and reduce greenhouse gas emissions.
3. Recyclability: Eco-friendly wetsuits are designed to be easily recyclable or biodegradable, so they don’t contribute to plastic pollution or waste in landfills.
4. Durability: Eco-friendly wetsuits are built to last, so they don’t need to be replaced as often as traditional wetsuits. This means fewer resources are used in the production of new wetsuits, and fewer wetsuits end up in landfills.
5. Fair labor practices: Eco-friendly wetsuits are often produced under fair labor practices, ensuring that the workers who make them are treated fairly and receive a living wage.
6. Transparent supply chain: Eco-friendly wetsuits often have a transparent supply chain, meaning that consumers can trace the origin of the materials used in the wetsuit and ensure that they are sustainably and ethically sourced.

By considering these aspects when purchasing a wetsuit, consumers can make a more environmentally-conscious choice and reduce their impact on the environment.

Yes, there are some environmental concerns associated with the production and disposal of wetsuits.

The production of neoprene, which is the primary material used in wetsuits, requires the use of petroleum-based chemicals and produces greenhouse gas emissions. However, some manufacturers are using more sustainable materials such as natural rubber or neoprene made from limestone instead of petroleum-based neoprene to reduce the environmental impact.

Additionally, wetsuits are not biodegradable and can take hundreds of years to break down in landfills. When wetsuits are disposed of, they can release harmful chemicals into the environment, such as chlorofluorocarbons (CFCs) that are used in the production of neoprene. Some manufacturers are implementing recycling programs for wetsuits, allowing them to be repurposed into other products such as yoga mats or car insulation.

Another environmental concern is the disposal of wetsuit packaging, such as plastic bags or cardboard boxes, which can contribute to plastic pollution and waste.

To minimize the environmental impact of wetsuits, consumers can choose to buy from environmentally-conscious brands that use sustainable materials and production methods, and dispose of their wetsuits responsibly by donating or recycling them. Additionally, taking care of your wetsuit and prolonging its lifespan through proper storage and maintenance can also help reduce the environmental impact of wetsuits.

1. Seam construction: The seams on a wetsuit can greatly impact its durability and longevity. Look for wetsuits with glued and blind-stitched seams, which are reinforced with a layer of wetsuit material and are less likely to leak or come apart than flat-lock seams.
2. Stitching: The stitching on a wetsuit should be tight and even, with no loose threads or fraying. Double-stitching and reinforced stress points can also help improve the durability of a wetsuit.
3. Zipper quality: The zipper on a wetsuit should be durable and corrosion-resistant, with a smooth, easy-to-use design. Look for wetsuits with high-quality zippers and reinforced zipper flaps to prevent water from entering through the zipper.
4. Fit and comfort: A well-fitting wetsuit that is comfortable to wear can greatly impact its durability and overall performance. Look for wetsuits that fit snugly but not too tight, with no gaps or sagging material. Wetsuits with ergonomic panel designs and features such as seamless underarms can also improve comfort and durability. Wetsuits with flush panels also allow any water that manages to enter the suit to be released near the ankles to avoid uncomfortable pooling.
5. Material: Wetsuits made from limestone are more durable than neoprene but also very expensive and the limestone must be mined.  Wetsuits made from Ecofoam are particularly durable, comfortable and have the additional virtue of being eco-friendly to the max.

The main difference between a wetsuit designed for surfing and one designed for other water activities, such as diving or swimming, is the thickness and flexibility of the neoprene.

Wetsuits designed for surfing typically have a thinner neoprene construction that allows for greater flexibility and range of motion, which is important for paddling and maneuvering on a surfboard. They typically range in thickness from 2mm to 4mm and may have additional features such as reinforced knee pads and seamless panels for greater comfort.

In contrast, wetsuits designed for diving or other water activities where the wearer is not actively moving as much, such as stand-up paddleboarding or kayaking, tend to be thicker to provide greater warmth in colder water. These wetsuits can range in thickness from 3mm to 7mm, depending on the water temperature and depth of the dive. They may also have additional features such as reinforced knee pads and wrist and ankle seals to prevent water from entering the suit.

Wetsuits designed for swimming are typically thinner than both surfing and diving wetsuits and often feature a sleeveless or short-sleeved design for greater range of motion. These suits are designed for open water swimming or triathlons, where the water temperature can be colder than a pool, and typically range in thickness from 1mm to 3mm.

Ultimately, the choice of wetsuit will depend on the specific water activity and conditions in which it will be used. It’s important to choose a wetsuit that is appropriate for the water temperature, provides adequate warmth and protection, and allows for a comfortable range of motion.

Yes, wetsuits can be worn for a variety of water activities beyond just surfing, including diving and swimming. Wetsuits are designed to keep the wearer warm in cold water by trapping a layer of water between the suit and the skin, which is then warmed by the body’s natural heat.

It’s important to choose the right type of wetsuit for the specific water activity you’ll be doing and the water temperature you’ll be in. Using a wetsuit that is too thick or too thin for the conditions can result in discomfort or even hypothermia.

Caring for and maintaining your wetsuit properly is important to prolong its life and ensure it performs well in the water. Here are some tips for taking care of your wetsuit:

1. Rinse your wetsuit after each use: Rinse your wetsuit with fresh water after each use to remove salt, sand, and other debris that can damage the material.
2. Hang your wetsuit to dry: Hang your wetsuit inside out in a well-ventilated area out of direct sunlight to prevent fading and damage to the neoprene.
3. Avoid using a dryer: Do not use a dryer or expose your wetsuit to direct heat sources, as this can damage the neoprene and other materials.
4. Store your wetsuit properly: Store your wetsuit flat or hanging on a wetsuit hanger to avoid creases and maintain its shape.
5. Avoid using harsh chemicals: Do not use bleach or other harsh chemicals to clean your wetsuit, as this can damage the neoprene and other materials.
6. Use a wetsuit shampoo: Use a wetsuit shampoo specifically designed for cleaning neoprene to remove dirt and odors from your wetsuit.
7. Oil buttons and zippers every at least twice a year.  A food grade silicone oil works well.
8. And don’t allow petroleum products near the suit.  And obviously, don’t iron the wetsuit!
9. Patch small tears and holes: Use wetsuit cement or a patch kit to repair small tears or holes in your wetsuit before they become larger problems.
10. Rotate between wetsuits: If you have multiple wetsuits, rotate between them to allow each wetsuit to dry completely between uses and prevent the buildup of odors and bacteria.

By following these tips, you can help prolong the life of your wetsuit and keep it in good condition for many surfing sessions to come.

Back-zip, chest-zip, and zip-free wetsuits differ in the way they are designed to allow the wearer to put them on and take them off. Here’s an overview of the differences:

1. Back-zip wetsuits: These wetsuits have a zipper on the back that runs vertically down the spine. The zipper allows the wearer to open up the back of the suit and easily step in and out of it. Back-zip wetsuits are the most common type of wetsuit and are often the most affordable. However, they can be less flexible and may allow some water to enter through the back zipper.
2. Chest-zip wetsuits: These wetsuits have a zipper on the chest that runs horizontally across the upper chest. The zipper allows the wearer to open up the front of the suit and step in and out of it. Chest-zip wetsuits are usually more expensive than back-zip wetsuits, but they offer greater flexibility and are less likely to allow water to enter through the zipper.
3. Zip-free wetsuits: These wetsuits do not have a zipper and are designed to be pulled on and off like a tight-fitting shirt. Zip-free wetsuits are the most flexible and can provide a more streamlined fit, but they can be more difficult to put on and take off, especially when they are wet.

Each type of wetsuit has its own advantages and disadvantages, and the best type of wetsuit for you will depend on your individual needs and preferences. It’s always a good idea to try on different types of wetsuits to see which one feels the most comfortable and provides the best fit for you.

A wetsuit should fit snugly but not so tight that it restricts your movement or causes discomfort. Here are some guidelines to follow when determining how tight a wetsuit should fit:

1. No excess fabric: A wetsuit should fit closely to your body, with no excess fabric or wrinkles that could create gaps and allow water to seep in.
2. Comfortable compression: The wetsuit should feel snug and provide some compression, but not so tight that it restricts your breathing or circulation.
3. Full range of motion: You should be able to move freely and comfortably in the wetsuit. Test this by bending your knees, raising your arms, and moving your torso to ensure the wetsuit doesn’t restrict your movement.
4. Minimal water entry: When wearing the wetsuit in the water, there should be minimal water entry. A small amount of water is normal and actually helps insulate your body, but too much water can make you feel cold and uncomfortable.

Keep in mind that the fit of a wetsuit can vary depending on the brand and model. Some types of wetsuits, such as chest zip or zip-free wetsuits, may require a tighter fit than traditional back zip wetsuits. It’s always best to try on a wetsuit before purchasing it to ensure a proper fit. If you’re unsure about the fit, consult with a wetsuit expert or the manufacturer’s customer service team for guidance.

Choosing the right size wetsuit is important for comfort and functionality. Here are some general steps to follow when determining the size of a wetsuit you need:

1. Take your measurements: Use a tape measure to measure your chest, waist, hips, and inseam. Record these measurements in inches or centimeters.
2. Check the size chart: Every wetsuit brand has its own sizing chart, so it’s important to check the manufacturer’s size chart before buying a wetsuit. Use your measurements to determine which size wetsuit you should try on.
3. Try on multiple sizes: It’s best to try on several wetsuits in different sizes to find the one that fits you best. Keep in mind that a wetsuit should fit snugly, but not be so tight that it restricts your movement.
4. Check the fit: When trying on a wetsuit, pay attention to the fit around the neck, arms, and legs. Make sure there is no excess fabric or gaps that could allow water to seep in. The wetsuit should feel comfortable and allow for a full range of motion.
5. Consider the type of wetsuit: Some types of wetsuits, such as chest zip or zip-free wetsuits, may require a tighter fit than traditional back zip wetsuits. Be sure to check the manufacturer’s recommendations for the specific type of wetsuit you are interested in.

Keep in mind that the size of a wetsuit can vary depending on the brand, style, and model. It’s always best to try on a wetsuit before purchasing it to ensure a proper fit. If you’re unsure about the size, consult with a wetsuit expert or the manufacturer’s customer service team for guidance.

The thickness of the wetsuit you need for the water temperature you’ll be surfing in depends on several factors, including your individual tolerance for cold, the length of your surf sessions, and the type of water activity you’ll be doing. Here are some general guidelines for wetsuit thickness based on water temperature:

1. 75°F and above: A 1-2mm wetsuit top, rash guard, or boardshorts are typically suitable for warm water temperatures.

2. 65°F-75°F: A 2-3mm full wetsuit is generally appropriate for water temperatures in this range. If you’re prone to feeling cold, consider a wetsuit with a thicker torso and thinner arms and legs, such as a 3/2mm.

3. 55°F-65°F: A 4/3mm or 3/2mm full wetsuit is recommended for water temperatures in this range. If the water is closer to 55°F, consider a 5/4mm or 4/3mm hooded wetsuit for added warmth.

4. 45°F-55°F: A 5/4mm or 6/5/4mm hooded wetsuit is recommended for cold water temperatures in this range. Some surfers may also choose to wear boots, gloves, and a hood for added warmth.

5. 45°F and below: A 6/5/4mm or 7/6mm hooded wetsuit is necessary for very cold water temperatures. You should also wear boots, gloves, and a hood to keep your extremities warm.

It’s important to note that these guidelines are not absolute and that everyone has different temperature preferences. If you’re unsure of what wetsuit thickness is appropriate for the water temperature you’ll be surfing in, it’s always best to err on the side of caution and choose a slightly thicker wetsuit.
