Whether you're a surfer, lifeguard, lunging sailor, kitesurfer, diver or paddleboarder, choosing the right neoprene wetsuit is essential if you want to get the most out of your sessions at sea, without ending up freezing (or completely sweaty). And the most important criterion is the water temperature.
In this article, Mellow Sea helps you see clearly so you can choose the right combination at the right time.
Why wear neoprene? 🌊
Neoprene is your best friend in the water. It insulates your body by trapping a thin layer of water between your skin and the suit. This water warms up with your body heat and keeps you warm. The thickness of the suit, its cut and its flexibility will make all the difference depending on the conditions.
Which wetsuit for which water temperature? 🌡️
Here's a quick guide to what to put on depending on the temperature:
| Water temperature | Recommended thickness | Type of combination |
|---|
| > 22°C | Lycra / Shorty 1-2 mm | Perfect for protecting you from the sun |
| 18-22°C | 3/2 mm | Lightweight integral, mid-season or summer |
| 14-18°C | 4/3 mm | Ideal for spring and autumn sessions |
| 10-14°C | 5/4/3 mm or 5/4 mm | Winter suit, with bonnet if it's windy |
| < 10°C | 6/5/4 mm + accessories | For the bravest or those addicted to cold water |
💡 With our ultra-stretch 100% neopreneEven a 5/4 mm gives you the same freedom of movement as a classic 3/2.
What about accessories? 🧤
When the water starts to drop below 15°C, remember to protect your extremities too:
- The balaclava To avoid ice cream headache as soon as you dip your head in.
- The gloves To keep your hands functional (so you can hold your paddle, for example).
- The slippers So you don't end up with frozen or cut toes on the rocks.
Heat + mobility: finally possible 🏄♂️
Traditionally, the thicker the suit, the less supple it is. But that was before.
Thanks to our neoprene 100% ultra stretchYou can take on the cold with a 5/4 mm or 4/3 mm, while retaining real freedom of movement. No need to sacrifice your fluidity of movement to stay warm.
