Which wetsuit thickness should I choose?Updated 10 days ago
Choosing the right wetsuit thickness is important for staying comfortable in the water. A wetsuit should keep you warm without overheating and allow you to move freely without restriction.
The ideal thickness depends on factors such as water temperature, weather conditions, activity level, and personal preference. Thicker wetsuits provide more insulation for colder conditions, while thinner wetsuits offer greater flexibility and are better suited for warmer temperatures.
Why Does Wetsuit Thickness Matter?
A wetsuit works by trapping a thin layer of water between the neoprene and your skin. Your body warms this layer, helping you stay comfortable in the water.
Choosing the correct thickness helps you:
- Stay warm in the conditions you are surfing, swimming, or paddling in
- Maintain comfort during longer sessions
- Maximize flexibility and freedom of movement
- Avoid overheating in warmer temperatures

What Does the "+" (Plus) Mean on a Wetsuit?
If a wetsuit is labeled as a "+" (Plus) model, it features an additional 0.5mm of neoprene thickness throughout the suit.
This extra insulation provides increased warmth while maintaining the flexibility expected from O'Neill's premium neoprene technologies.
