Support the young startup of a former competitive athlete
My name is Sebastian, I've been playing golf for over 20 years and I was fed up with polyester clothing that makes you sweat, stick and smell.
That's why I founded Serino in 2024. We make clothing from wood fibers that keeps you cool, dry, and fresh all day long.
Sebastian , founder of Serino
No sweating, no sticking, no sweat smell
Sportswear for those who are tired of polyester
With Serino Natural Sportswear made from wood fibers, you'll feel light, free, and comfortable all day long – whether you're exercising, at the office, or enjoying your free time.
The revolution in sportswear
Why wood fibers are a better choice than polyester and cotton
Unlike polyester, which traps heat, retains odors, and feels artificial, wood fibers are breathable, cooling, and odor-resistant. They feel silky soft, wick moisture quickly, and dry quickly.
They also score points over cotton: wood fibers are lighter, dry faster and feel even softer.
Wood fibers like Modal or Lyocell are made from sustainably sourced beech or eucalyptus wood – in a resource-saving cycle. So, they're not only good for you, but also for the environment.
