Story of MerinFit

It all started with a simple truth: sports are meant to improve our health, not harm it.
Yet every day, millions of athletes train in polyester shorts. Behind their apparent practicality, these fabrics hide a silent problem: they’re made of plastic. When exposed to heat and sweat, this plastic releases microfibers and chemicals that penetrate the skin. Over time? Irritation, stubborn odors, trapped sweat… and long-term health risks.

At MerinFit, we refused to accept that.
We asked ourselves a question: why keep sweating in plastic when nature already offers healthier, high-performance fibers?

That’s when the idea of creating a different short was born.
We chose merino wool, an extraordinary natural fiber: breathable, antibacterial, luxuriously soft like cashmere, and able to regulate body temperature even during intense training. Paired with organic cotton, it delivers a sustainable alternative that respects your health.

MerinFit isn’t just a clothing brand — it’s a mission.
Our goal is to let athletes perform without compromise — no sticky sweat, no lingering odor, and no plastic harming their body.

We decided to create the short we always wanted to wear:
✔ 100% natural
✔ breathable and comfortable
✔ respectful of your health and the planet

With MerinFit, you’re not just wearing shorts.
You’re choosing a healthier, more natural, and future-focused way of training.
