The O'Neill Basic Skin Sun Shirts are equipped with world-renowned O'Neill quality. The lycra with 50+ UV protection is water-repellent and made from very light fabric. UV protection is a particularly important topic in summer, but UV radiation on the water should not be underestimated at other times of the year either. Frequent exposure to the sun is the cause of various forms of skin damage, including premature skin ageing and even skin cancer. O'Neill UV shirts absorb and block most of the sun's rays. O'Neill UV products are designed with elastic threads that are flexible enough to pull fibres together extremely tightly, effectively minimising the sun's harmful rays. This second layer of skin not only protects you from the sun, but also prevents rashes from surfboards and provides warmth in cool conditions.
