      The Problem: Polyester

      Behind its low price, polyester hides a troubling reality. Made from petroleum, it releases microplastics with every wash, suffocates the skin, traps odors, and exposes the body to harmful chemicals. The result: a cheap fabric that pollutes the planet and harms your health.

      The Solution: MerinFit™

      At MerinFit™, we’ve made a clear choice: replacing polyester with natural, certified fibers, with merino wool at the heart of our creations. Our clothing breathes with you, regulates your temperature, and naturally prevents unpleasant odors. Gentle on the skin and free from microplastics, it protects both your health and the environment. With MerinFit™, you’re wearing more than just clothing – you’re embracing a new way of taking care of yourself and the planet.

      I can’t believe I spent years sweating in plastic shorts. Once I switched to Merinfit, 100% natural Merino shorts, everything changed. No more chafing or itching. They’re insanely soft, regulate temperature like a dream, and let me focus on lifting instead of adjusting uncomfortable seams. My performance feels better because I’m not overheating or sweating in chemicals. I’m never going back to polyester again.
