“Nature is my playground – whether in the mountains or on the beach.”
Joël Portner ( @ joe.tethar ), 24, lives for movement and the outdoors. Whether freeriding, ski touring, kitesurfing, or road cycling, Joël always finds a way to enjoy nature and challenge himself. "Nature gives me energy and balance, and NIKIN embodies precisely these values," he says.
"When I was 16, I went kitesurfing in Madagascar—an unforgettable experience, unfortunately also for my leg," Joël recalls with a laugh. After a spectacular landing, he was left with an open fracture of his tibia and fibula—and the whole thing was captured in crystal-clear 4K quality. But Joël wouldn't be himself if he let that stop him.

Whether shopping or making daily decisions, Joël takes sustainability seriously . "For me, sustainability means respecting the planet so that future generations can also benefit from it." His support of brands like NIKIN is a conscious step to be part of a positive change.

Joël has a weakness for versatile fashion that's functional and sustainable. "The sleeveless TreeTank shirt is my absolute favorite. It goes with everything – for sports, at the beach, or just for fun."
Why Joël is passionate about NIKIN
"Combining fashion and sustainability is a concept I fully support," explains Joël. As a NIKIN ambassador, he wants to inspire young people to choose Swiss brands and make a positive contribution to the environment. "It's cool to look stylish and do something good at the same time."

“I love sports, I like to share my knowledge – and raclette is a must!”
With his passion for fitness and outdoor activities, Joël is a true team player. His positive energy and commitment make him a great asset to the NIKIN community.
Joël Portner demonstrates how sport, sustainability, and a conscious lifestyle can go hand in hand.
