Our Impact: Natural-Fiber Activewear, Low-Tox Clothing, and Plastic-Free Packaging

We create activewear from 95% natural fibers (merino wool) with a focus on skin-safe, low-tox materials that support your wellbeing. Our packaging is 100% plastic-free, and every part of our supply chain is designed to minimise microplastic shedding, reduce chemical exposure, and lower environmental impact.

Why Natural Fibers Matter in Activewear

Most activewear today is made from polyester, nylon, and synthetics that shed microplastics, trap heat, and rely on chemical treatments. We take a different approach. Natural fibers are breathable, sweat-safe, and kinder to the skin. They reduce chemical exposure and minimise the release of microplastics into your home and the environment.

95% Natural Fiber Construction

Every piece is crafted using a high-performance natural fiber blend: 95% merino wool with 5% elastane for shape and support. Merino is naturally temperature-regulating, antibacterial, and moisture-wicking without the need for chemical finishes. This means fewer toxins, reduced friction on sensitive skin, and a more grounded connection between your body and the materials you wear daily.

Zero Plastic Packaging

Our commitment extends beyond the garment. All packaging - including garment bags and shipping boxes—is entirely plastic-free. We use cardboard product envelopes and boxes for shipping that leave no microplastic trace. No virgin plastics. No petrochemical films. Just thoughtful, low-impact packaging designed for easy disposal and minimal waste.

A Low-Tox, Skin-Friendly Philosophy

We avoid the harsh chemical dyes used in most activewear. No synthetic finishes that disrupt the skin barrier. Our manufacturer uses threads, dyes, fibers and processes that are OEKO TEX certified.

Our Path Forward

We know sustainability is ongoing. We are continually refining our materials, manufacturing, and packaging to further reduce our footprint. Our goal is to create the most skin-safe, planet-conscious activewear possible, without compromise. We welcome feedback or recommendations please email us at hola@estroni.com.au.
