Wetsuit Essentials: Choosing the Right Fit and Material

When exploring the world of water sports, a wetsuit is an essential gear that allows you to maintain body warmth in cooler waters. Made from neoprene, these suits come in various thicknesses, suitable for different water temperatures and activities. Whether you’re diving, surfing, or participating in other aquatic sports, a wetsuit helps to increase your comfort and performance by providing thermal insulation and some buoyancy.

The design and fit of a wetsuit are crucial for its function. It should be snug enough to form a thin layer of water between you and the suit, which your body then heats, providing an insulating barrier. However, a suit that’s too tight can restrict movement and be uncomfortable. Options range from full suits, which cover your entire body, to spring suits, which have shorter arms and legs, depending on your needs and the conditions you will be facing.

When selecting a wetsuit, you’ll need to consider the thickness, which is usually measured in millimeters, and the cut that’s best for your activities. The thicker the neoprene, the warmer the suit will be. Advanced features, such as sealed seams, can also improve water tightness and warmth. With a proper wetsuit, you can extend your time in the water, enhance your performance, and enjoy water activities even in cooler temperatures.

History of Wetsuits

Your understanding of wetsuits starts with Hugh Bradner, a physicist who, in the early 1950s, recognized the need for improved insulation for divers. While working with the University of California, Berkeley, Bradner conceived the idea of trapping water between the suit and the skin to maintain body heat, which led to the creation of the first neoprene wetsuit.

The evolution of wetsuits is characterized by gradual improvements in materials and design. Initially, neoprene was sandwiched between layers of nylon or spandex to improve durability. Over time, manufacturing techniques became more sophisticated, allowing for better fit and enhanced seam sealing.

The success of Bradner’s wetsuit concept eventually sparked competition and innovation within the industry. Jack O’Neill, among others, played a significant role in popularizing wetsuits for various water sports. Their insulative properties significantly extended the time individuals could spend in the water, revolutionizing water activities like surfing, diving, and windsurfing.

Your appreciation for this apparel grows with the knowledge that wetsuits not only provide thermal protection but also safety from abrasion, UV exposure, and marine stings.

Materials and Fabrication

When choosing a wetsuit, it’s essential to understand the role of materials used and their fabrication process as they dictate the suit’s performance, comfort, and durability.

Neoprene Types

Neoprene is the core material in wetsuit construction, offering thermal insulation and flexibility. The quality of neoprene varies with the specific composition and manufacturing process. Some wetsuits utilize Yamamoto neoprene, which is known for its higher flexibility and better insulation. High-grade neoprene, distinguished by higher numbers like #39 and #40, enhances the wetsuit’s performance and fitting.

Fabric Linings

The fabric linings bonded to neoprene sheets are crucial for comfort and durability. Internal linings often vary, with some designed for additional warmth, while others aim at increasing flexibility. Common lining materials include nylon and polyester, complementing the neoprene’s properties and affecting the wetsuit’s overall feel.

Seam Construction

Seams significantly impact a wetsuit’s strength and water tightness. Basic wetsuits have flatlock seams, suited for warmer waters. For colder conditions, sealed seams that are glued and blind-stitched provide enhanced, water-resistant seals. Some high-end wetsuits feature taped or welded seams for maximum integrity and minimal water entry.

Wetsuit Types

When you’re selecting a wetsuit, the main types you’ll encounter are full wetsuits, spring suits, and shorties. Each serves a specific purpose, depending on water temperature and desired mobility.

Full Wetsuits

Full wetsuits cover your entire body—torso, arms, and legs—and are designed for use in colder waters. They come in varying thicknesses, typically ranging from 3 mm to 6 mm, directly correlating with the water temperature they can handle. A full wetsuit is your go-to for most surfing, diving, and open-water swimming needs in cooler environments.

• Thickness:
  • 3 mm (warm water)
  • 4 mm (moderately cold water)
  • 5/6 mm (cold water)

Spring Suits

Spring suits provide coverage to the torso and upper parts of your legs and arms. They are ideal for use during warmer conditions or during transitional seasons like spring and fall. Often constructed with a neoprene thickness of around 2 mm, spring suits offer a balance between warmth and flexibility, allowing for more freedom of movement.

• Coverage:
  • Torso
  • Thighs
  • Upper arms

Shorties

Shorties, or shorty wetsuits, are similar to spring suits but with even shorter arms and legs. The typical design covers your torso and shoulders and includes shorts that extend to mid-thigh. Best suited for warm water environments, shorties are a popular choice when minimal insulation and maximum range of motion are priorities.

• Design:
  • Short sleeves
  • Short legs (mid-thigh)

Remember, the right wetsuit type not only contributes to your comfort and warmth but also enhances your overall performance in the water.

Design Features

Wetsuit design features enhance performance, comfort and flexibility in water. Each element plays a critical role in function and fit.

Zippers

Your wetsuit might have a back zipper which allows for easy entry and exit. This traditional style of zipper is known for its convenience. Alternatively, a chest zip design offers a better water seal and can enhance upper body flexibility while swimming.

Seals and Flaps

To prevent water from entering, wrist and ankle seals are crucial. These tight-fitting closures ensure minimal water exchange. Additionally, zipper flaps offer extra protection against water entry and can also prevent the zipper from causing discomfort against your spine.

Thermal Properties

The heart of a wetsuit’s warmth lies in its neoprene construction. Neoprene comes in varying thicknesses, typically measured in millimeters. The thicker the neoprene, the warmer the suit. For colder conditions, you might consider a suit with a thermal lining for additional heat retention.

Fit and Sizing

Finding the right wetsuit is crucial for both comfort and performance in water activities. It’s important to know your measurements and how a wetsuit should feel once on.

Measuring Guides

Begin by accurately measuring your height, weight, chest, and waist. For males and females, chest measurement is the most critical, as it influences the overall fit the most. Consult wetsuit size charts to cross-reference your measurements with the sizes available for various brands.

• Height: Measured from the top of your head to the bottom of your feet.
• Weight: Best taken in the morning for more accuracy.
• Chest: Measure around the widest part of your chest.
• Waist: Measure around your natural waistline.

Remember, different brands may have slight variations in sizing, so always check the brand’s specific size chart.

Fit Considerations

A proper-fitting wetsuit should feel like a second skin, tight but not constrictive. While putting on the wetsuit, ensure that there are no excess gaps and that it allows for full range of motion. Pay attention to the fit around your neck, back, and knees, where water can seep in if the suit is too loose.

• Tightness: The wetsuit should be snug, as a looser wetsuit can cause chafing.
• Comfort: While needing to be tight, ensure breathing is not restricted.
• Neoprene Stretch: Neoprene will stretch slightly over time, so a snug fit initially is acceptable.

In between sizes? Some brands offer “Long” or “Short” versions to better accommodate different body shapes. If you’re in between sizes, exploring different brands or specific models might yield a better fit. Opting for a custom-tailored wetsuit is another solution if you’re unable to find an optimal off-the-rack fit.

The chart below is a general guide to help you start with finding the right wetsuit size. Remember, the fit should be snug but not restrictively tight, as a properly fitting wetsuit will keep you warm and allow for maximum mobility in the water. Always try on a wetsuit if possible before purchasing, and consider any specific needs you might have, such as additional room in certain areas or preference for a tighter fit to ensure minimal water entry.

Performance and Mobility

In triathlon wetsuits, your performance and mobility are influenced by the suit’s stretch and flexibility, as well as the buoyancy it provides.

Stretch and Flexibility

Your wetsuit should allow for maximum stretch and flexibility to enable a full range of movement, which is crucial during the swim portion of a triathlon. High-quality wetsuits often leverage advanced materials that offer significant stretch without sacrificing durability. These materials, such as Yamamoto neoprene, enhance your ability to move freely and maintain an efficient stroke.

Buoyancy Effects

Buoyancy plays a pivotal role in maintaining a good swimming posture by providing hydrostatic lift. This lift helps bring your body into a more streamlined position, thus reducing drag. Wetsuits with targeted buoyancy zones can assist in elevating your lower body, equating to less fatigue and improved swim times. It’s important to choose a wetsuit with the right level of buoyancy to complement your body composition and swimming style.

Buoyancy in wetsuits refers to the ability of the suit to help the wearer float in water. This characteristic is particularly important for activities such as scuba diving, snorkeling, and swimming, where controlling your position in the water is crucial. The buoyancy level of a wetsuit is influenced by several factors, including the thickness of the neoprene, the type of neoprene, and the suit’s overall design. Here’s a breakdown of how these factors affect a wetsuit’s buoyancy:

Thickness

• Thicker Neoprene: Provides more buoyancy because thicker neoprene contains more nitrogen gas bubbles, which are responsible for the flotation effect. Wetsuits can range from about 2mm (thin, less buoyant, suitable for warm water) to 7mm (thick, more buoyant, designed for cold water). The thicker the wetsuit, the more buoyant it will be, but it will also be less flexible.

Type of Neoprene

• Closed-cell Neoprene: Most traditional wetsuits are made from this type, which has gas bubbles encapsulated within the material, providing inherent buoyancy.
• Open-cell Neoprene: Has a different internal structure and is generally used in spearfishing suits. It can offer buoyancy but is more focused on insulation and flexibility.

Suit Design

• Full Suits vs. Shorties: Full suits cover more of the body and can offer more buoyancy due to the increased amount of neoprene. Shorties (short-sleeved and ending above the knee) contain less neoprene, making them less buoyant but more suitable for warmer conditions.
• Additional Buoyancy Aids: Some wetsuits incorporate additional buoyancy aids, such as integrated air pockets or neoprene that has been specially treated to increase its buoyancy. These suits are particularly useful for beginners in water sports who may require extra help with flotation.

Considerations

• Water Temperature: Thicker wetsuits, while more buoyant, are also warmer. The choice of wetsuit thickness and, consequently, its buoyancy level, should consider the water temperature you’ll be entering.
• Activity Type: Activities that require deeper submersion or more flexibility might benefit from a less buoyant wetsuit, allowing for easier movement underwater.

Adjusting Buoyancy

For activities like scuba diving, where precise buoyancy control is essential, divers often use weight systems in conjunction with their wetsuits to counteract the buoyancy and achieve neutral buoyancy underwater.

Care and Maintenance

Proper care will significantly extend the life of your wetsuit. Ensure that you clean, store, and repair your wetsuit correctly, which keeps it functional and comfortable.

Cleaning Procedures

• After Each Use: Rinse your wetsuit with cool, fresh water to remove salt, chlorine, and other debris. Turn the suit inside out to ensure both sides are thoroughly cleaned.
• Deep Cleaning: Occasionally, use a wetsuit-specific cleaner and soak for a short period, then rinse thoroughly. Avoid using harsh detergents as they can damage the neoprene.

Storage Tips

• Avoid Folding: Store your wetsuit flat or on a wide hanger to prevent creases and maintain the neoprene’s integrity.
• Proper Environment: Keep it in a cool, dry place away from direct sunlight to prevent the neoprene from degrading.

Repair Techniques

• Small Tears: Use neoprene cement to bond tears and holes. Apply a thin layer, press firmly and allow it to dry completely.
• Seam Damage: If seams split, they can be repaired with a neoprene adhesive or, for a stronger fix, sewn using nylon thread and then sealed with liquid seam sealant.

Environmental Impact
