The American former Olympic skiing champion, 37, flaunted her physique in a metallic swimsuit.
She posed for Yniq Eyewear in a pair of blue goggles.
Sharing a snap on social media, she wrote: “My ski goggles don’t work as well on the beach…so I created something new.”
Lindsey announced her retirement from alpine skiing in 2019 after covering the 2014 Winter Olympics in Russia.
Her career stretched 19-years, winning four World Cup championships and competing in four Olympics.
She gravitated towards ski racing at a young age thanks to her father, Alan Kildow, who won a national junior title at the age of 18 before a devastating knee injury.
