Decent foam at this price

I am satisfied with the purchase. The water actually pours in through the collar, but at the current temperatures (mid-September) you can live with it. Reasonable price. I would buy again.

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 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).

Return policy

Any doubts regarding the wetsuit size you should choose when placing your order? Returns and exchanges are free at the customer service desk in our stores for a period of 365 days if your purchase is recorded on your Decathlon account. You can also return your wetsuit through the post or at a pick-up point by printing your return form on our website, under: My Purchases. In such a case, you are responsible for the cost of returning the items.


This OLAIAN 100 4/3 mm wetsuit is made from genuine neoprene for guaranteed optimal comfort during use.The neoprene is lined with synthetic fabric for increased resistance to wear.Neoprene thickness: 4 mm and 3 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. 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.

Key pocket

There is a key pocket under the zip flap.

Product testing

Developed and tested by our design teams in Hendaye, France. The components used for this product are laboratory-tested to ensure the best possible quality and durability.

Storage instructions

In a dry, well-ventilated place. Avoid heat sources. To extend the life of your wetsuit, do not leave it out to dry in direct sunlight. Machine washing is not recommended.
