The uvex heyya is a children's helmet designed for the highest standards. Thanks to its in-mold technology, it is not only extremely safe but also incredibly lightweight. So light that children can hardly feel it on their heads. This is also ensured by the IAS adjustment system, which allows the uvex heyya to be precisely tailored to every child's head, and the Monomatic closure, which is easy to operate even with gloves. Another advantage: The ventilation system provides enough fresh air for children's heads even during the most intense snow adventures. Combined with the comfort padding inside the helmet, even the little ones experience maximum wearing comfort.
