UYN - Unleash Your Nature, the Italian brand of functional apparel, has announced Aymar Navarro as a new ambassador for the brand. The 31-year-old freeride athlete will be supported in his races by UYN technical underwear and socks made of Natex fabric, an exclusive bio-fiber derived from castor oil seeds. He is expected to wear UYN’s high-tech apparel also in his training and everyday life, the brand said. In 2015, Navarro became the first Spanish skier to take part in the Freeride World Tour, the most prestigious freeride skiing and snowboarding competition in the world. In 2017, he earned the title of European Skier of the Year, becoming the first Spaniard to receive the honor. Navarro made his debut with UYN in the first stage of the Freeride World Tour on Feb. 19 in Andorra, where he finished sixth.
