How to choose the right wetsuit (Part 1)

The first selection criterion when choosing a surfing wetsuit is the water temperature.

Water temperature varies according to the location and the time of the year.

Systematically make sure that the water temperature at your spot corresponds to the recommended temperature range:

Warm water above 20°C. Temperate water between 17°C and 22°C. Cold water between 12°C and 17°C. Very cold water between 7°C and 12°C. Visit the site seatemperature.org to find out the temperature of your spot.

How to choose the right wetsuit (Part 2)

The 2nd criterion to take into account is the length of your sessions. If your sessions last less than an hour, the 100 models will be suitable. For up to 2 hours, opt for the 500 models and for up to 3 hours, the 900 models. Compared to the 100 models, the 500 models will be warmer (and more watertight) and more efficient at reducing fatigue (more freedom of movement) and irritation. The same is true for the 900 models compared with the 500 models. NOTE: the 900 models are easier to put on.

Choose the right size

To make the most of the features of your wetsuit, it is necessary to choose the correct size. A surfing wetsuit should be a very tight fit and there should be no visible folds. When dry, it is perfectly normal to feel like it is too tight, this discomfort disappears as soon as the wetsuit gets wet. If you choose a diving suit that is too big, folds will appear, you will experience irritation and thermal comfort will be reduced (letting in water).

This OLAIAN 500 3/2 wetsuit is made from genuine neoprene for guaranteed improved comfort during use.

The neoprene is lined with synthetic fabric for increased resistance to wear.

Neoprene thickness: 3 mm and 2 mm

The neoprene is made from an elastomer foam with insulating properties. We test and guarantee the quality of our neoprene materials.


The neck finish has been developed to limit irritations. According to the sensitivity of the wearer, a UV top can be worn under the wetsuit to reduce the risk of irritation. The application of grease (e.g. Vaseline) in friction areas (neck, underarms) is also recommended if wearing the diving suit for long periods.

Make sure the flap is always inside the wetsuit to limit the risk of irritation with the zip and the neck.


Our zips and fastenings are laboratory tested in order to ensure an optimal lifespan and good resistance to salt water. We have put the zip at the back of the wetsuit for more comfort during surf sports (when lying down to paddle).

Watertight assembly

The seams are stitched and glued to guarantee waterproofing and resistance. The seams are blind-stitched, which means the thread does not pass through the entire thickness of the neoprene and so prevents water from getting through. The absence of threads on the inside avoids irritation and chafing.

Comfort and reinforcement patches are strategically placed on the inside in sensitive areas.

Key pocket

There is a key pocket under the zip flap.

Anti-chafing design

We designed this product with seamless panels under the arms to limit irritation due to the repetitive paddling movements associated with surf sports.

Stay warm for longer thanks to our thermal accessories! Each temperature range has its own outfit...

When we are in the water, we lose more than half of our body heat through our extremities (feet, hands, head). Consequently, here are the recommended accessories:

- in warm water and temperate water (>17°C) => neoprene low booties.

- in cold water (12–17°C): High booties (boots) and gloves.

- in very cold water (7–12°C): High booties (boots), gloves, hood and hooded top.
