Understanding Wetsuit Thickness

Wetsuit thickness is measured in millimeters (mm) and is based on the internal foam core.

Thicker foam cores provide warmth, while thinner cores offer lightweight and flexibility.

Water temperature is the main factor in determining the right thickness wetsuit for you.

Thicker wetsuits are warmer, but less stretchy, while thinner wetsuits are more flexible but less insulating.

The thickness of the wetsuit depends on the water temperature and your personal preference.

Wetsuit Temperature Guide

A wetsuit’s thickness is crucial for surfing in cold water. Choosing the perfect wetsuit involves considering both the water temperature and your personal comfort preferences. The best wetsuit choice ultimately comes down to personal preference and water temperature. Consider whether you prefer more flexibility and freedom in the arms or more complete coverage. Thicker wetsuits (e.g., 4/3mm) are best for colder water, while thinner wetsuits (e.g., 2mm) are best for warmer water. Wetsuit thickness can also affect the level of warmth and insulation provided.

  • Consider factors such as water temperature, personal cold-tolerance, and activity level when choosing a wetsuit.

How Wetsuits Work

  • A wetsuit insulates body heat to keep you warm in cold water.
  • Most wetsuits have three layers: neoprene, lining, and insulation.
  • The neoprene and lining combine to keep water from entering the suit, while body heat warms up the water inside.
  • Wetsuits are not meant to keep you entirely dry, but rather to keep you warm.

The science behind wetsuit warmth

  • Wetsuits work by trapping a thin layer of water between your body and the suit.
  • The neoprene material provides insulation against cold water by trapping heat.
  • The trapped water is warmed by your body heat, keeping you warm in cold water.

The importance of wetsuit fit

  • A wetsuit should fit like a second skin with no sagging or bunching.
  • The suit should fit tight to keep only a thin layer of water between your body and the suit.
  • Fit is crucial for both warmth and mobility.

Wetsuit Fit Explained

  • A wetsuit should fit snugly but not too tightly, allowing for mobility and comfort.
  • Check for strong seals around the neck, wrists, and ankles, and make sure the neoprene fits tightly in these areas.
  • Avoid wetsuits with excess, wrinkly, or baggy areas of neoprene, especially in women’s wetsuits.

Common fit mistakes to avoid

  • Avoid wetsuits that are too small, as they can be uncomfortable and restrict movement.
  • Avoid wetsuits that are too large, as they can allow cold water to enter the suit.
  • Make sure to check the sizing chart for each brand, as they may vary.

Wetsuit Construction

Wetsuits are made from a material called neoprene, which is extremely elastic, durable, and insulating.

The neoprene comes in various thicknesses, and the numbers on the wetsuit indicate the thickness of the neoprene. A lightweight and flexible wetsuit provides solid warmth relative to its weight, emphasizing the durability and sustainability of the materials used, often incorporating recycled materials to enhance stretch and comfort.

Wetsuits can be springsuits, fullsuits, or shorties, and each type is designed for specific water temperatures and surfing conditions.

Wetsuit entry systems (Back Zip, Chest Zip, Zipperless)

  • There are three types of wetsuit entry constructions: back zip wetsuits, chest zip wetsuits, and zipperless wetsuits.
  • Back zip wetsuits have a zipper going down the length of the spine.
  • Chest zip wetsuits are entered through a zippered cutout around the neck.
  • Zipperless wetsuits eliminate the lack of flex found around zippered areas and stitching.

Wetsuit seam types (Flatlock, Glued and Blindstitched, Liquid Sealed and Taped)

  • A wetsuit is made by fusing multiple panels of neoprene together.
  • The seam plays a critical role in the overall warmth, flexibility, and comfort of a wetsuit.
  • Flatlock seams are stitched inside and out and are common on warm-water wetsuits.
  • Glued and Blindstitched Seams (GBS) are glued, fused, and then stitched together on the outside without piercing through.
  • Liquid Sealed and Taped Seams are common in high-end wetsuits designed for cold water.

Lined Wetsuits

  • A lining is an extra insulating layer on the inside of a wetsuit, which can add warmth and flexibility.
  • Lined wetsuits are available in different thicknesses and styles, and can be a good option for cold water surfing.
  • However, lined wetsuits may not be necessary for warm weather surfing, and can add bulk to the suit.

What is a lined wetsuit?

  • A lined wetsuit is a wetsuit with an extra insulating layer on the inside.
  • The lining can add warmth and flexibility to the wetsuit.

Wetsuit Accessories

  • Wetsuit accessories, such as neoprene accessories, can help keep your head, hands, and feet warm, contributing to your core warmth.
  • The three main categories of surf accessories are:
  • Wetsuit accessories
  • Neoprene accessories
  • Wetsuit

Boots

  • Neoprene and rubber boots for cold water activities.
  • Wetsuit booties can have a round toe or split toe.

Gloves

  • Neoprene gloves or mittens for cold water activities.
  • Five-finger gloves provide the most dexterity, while mittens are best suited for very cold water.

Hoods

  • Hoods can be added to hoodless wetsuits for additional warmth in colder waters.
  • Some wetsuits have hoods built-in.

Neoprene beanies

  • Light shirts made out of Lycra or other UV-resistant materials.
  • They are used to protect against sun and sand, and sometimes worn under a wetsuit.

Surfing in Cold Water

  • Thicker wetsuit options for cold water

A winter wetsuit is essential for maintaining warmth in extremely cold water conditions. Thicker wetsuit options for cold water provide better insulation and are crucial for surfers who brave the waves in colder climates.
