Stretch seams. * Easy dressing: Zip down the back. Long zip pull from 10 years. * Waterproof: YULEX100 1.5 mm natural rubber. Zip flap. Must be a tight fit. **Technical information:** 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 insulation will be reduced (letting in water). Try it on before you buy it! ; Neck: 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. It is also advisable to apply a greasy cream to areas of friction (neck, armpits) if you are going to use it for a long time. Make sure the flap is always inside the wetsuit to limit the risk of irritation with the zip and the neck. ; Fastening: 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). ; Zip pull: We are required by law to put a short cord on the zips of junior products to prevent the risk of strangulation for the youngest users. Above size 10 years, the cords are long so that the kids can use them by themselves. A small rip-tab prevents accidental opening of the zip during use. ; 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.
