Product Customer Reviews

The suize guide suggested Size L because of my hip and chest measurements, luckily I ordered size M too, because I could see size L being to large heightwise. I´m 1,73 and size M fits perfectly. Hip was 97 and Chest 85.
Wish the neck had a better seal
Great wetsuit! 5’7” 175lbs and the Men’s Large fit well!
fits very well and good freedom of movement for paddling in my packraft, good value for money
Good value for money
This is the first wet suit I had. It is easy to put on and it fits quite well. The only thing what could be a bit better is how it fits around the neck, as it is quite loose.
Really warm, well made and waterproof wetsuit to brave the cold North Sea
Good value for money
Thank you David!

Perfect
Have worn it twice and it's worked fine, pretty much as expected. I'm 5'11" and just under 14 and a half stones and the XL fitted me fine. It felt a little tight lengthwise i.e. pulling down on my shoulders, but both legs and arms were plenty long enough. Only complaint is that there was no key pocket as advertised.
Good value.
Returned to store for exchange , no problem at all . Staff very helpful
I'm happy with this wet suit. and I recommend it to anyone who wants to spend a lot of time in cold water.
Not good fit and quality below average
Even the cold of Newquay Bay wasn't that noticeable in this wetsuit

How to choose the right wetsuit (part 1)
The 1st 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 68°F. Temperate water between 63 and 72°F. Cold water between 54 and 63°F. Very cold water between 45 and 54°F. 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.NB: 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 wetsuit that is too big, folds will appear, you will experience irritation and thermal comfort will be reduced (letting in water).Try it on before you buy it!
Materials
This OLAIAN 100 4/3 wetsuit is made from genuine neoprene for improved comfort during use.The neoprene is lined with synthetic fabric for added 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.
Neck
The neck finish has been developed to limit irritation. 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 wetsuit for long periods. Make sure the flap is always inside the wetsuit to limit the risk of irritation with the zipper and the neck.
Fastening
Our zippers and fastenings are laboratory-tested in order to ensure an optimal lifespan and good resistance to salt water. We have put the zipper 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 for a watertight seal and durability. 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 zipper 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.
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, 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.
