The thickness of the neoprene is a crucial factor when choosing the right suit for water sports, as it provides thermal insulation and comfort in function of water temperature.
Below, I provide a guideline regarding the recommended neoprene thickness according to water temperature:
Neoprene thickness chart according to water temperature
| Water temperature | Neoprene thickness | Recommended suit type |
|---|---|---|
| > 24°C | 0.5 mm - 2 mm | Shorty or neoprene top |
| 18°C - 24°C | 2 mm - 3 mm | Short or long suit (2/2 mm or 3/2 mm) |
| 15°C - 18°C | 3 mm - 4 mm | Long wetsuit (3/2 mm or 4/3 mm) |
| 12°C - 15°C | 4 mm - 5 mm | Long wetsuit (4/3 mm or 5/3 mm) |
| 9°C - 12°C | 5 mm - 6 mm | Long wetsuit (5/4 mm or 6/5 mm) |
| < 9°C | 6 mm - 7 mm + thermal accessories | Semi-dry or dry suit (6/5 mm or 7 mm) |
Other factors to consider when choosing the thickness of your neoprene
-
Thermal accessories:
- At low temperatures (< 15°C), it is essential to wear gloves, booties, and a neoprene hood to prevent heat loss from the extremities.
- Choose thicknesses between 3 mm and 5 mm for accessories in cold waters.
-
Weather conditions:
- If there is wind, it is better to opt for a slightly thicker suit, as the effect of the wind can increase the feeling of cold (wind chill).
-
Duration of the activity:
- If you plan to spend a lot of time in the water, additional thickness can be more comfortable, even in warmer waters.
-
Mobility level:
- The thicker the material, the less flexibility. It is important to balance thermal protection with freedom of movement, especially in sports like surfing, kitesurfing, or wing foiling.
With this guide you will be able to choose the thickness ideal for enjoying your favorite water sport with comfort and safety.
Why a 4/3 neoprene?
A neoprene 4/3 mm is ideal for water temperatures in the range of 12°C to 15°C, although it may extend slightly depending on weather conditions and each person's cold tolerance.
- 4 mm in the torso: Provides greater thermal insulation in the trunk, which is where the body loses the most heat.
- 3 mm at the ends: Offers flexibility and mobility for the arms and legs, facilitating movements such as rowing or maneuvering.
When to use a 4/3 wetsuit?
- Ideal for spring, autumn and mild winter in waters with cool temperatures.
- If there is strong wind or you plan to be in the water for long hours, this thickness can be very useful even in waters of 15°C, combining it with accessories like a hood, booties, and gloves if necessary.
It is a versatile option for surfing, kitesurfing, wing foiling, and other water sports in cool climates, without reaching very cold water conditions (<12°C), where a thicker suit (5/4 mm or more) would be necessary.
