Activewear is something you wear close to your skin, often for hours at a time. Yet, many people never stop to consider what their leggings, sports bras or tops are actually made of.

As awareness grows around non-toxic and biodegradable activewear, more people are seeking better alternatives that support both their wellbeing and the planet.

At Wellicious, we believe that what you wear should support your wellbeing and never compromise it. Here are three things your activewear should never contain.

1. Toxic Chemicals in Activewear

Many conventional activewear brands use chemical treatments to achieve performance features such as moisture wicking, stretch or colour durability.

However, these can include harmful substances such as PFCs, formaldehyde and azo dyes. These chemicals can come into direct contact with your skin, especially when you sweat and your pores are more open.

What to look for instead:
Choose non-toxic activewear made from certified materials that have been tested for safety. Your skin is your largest organ, so what touches it matters.

2. Non Recyclable, Linear Materials

Most conventional activewear is made from synthetic blends that are difficult or even impossible to recycle.

This means that once a garment reaches the end of its life, it often ends up in landfill or incineration, contributing to the growing problem of textile waste.

What to look for instead:
Look for circular activewear, where materials are designed to be reused, recycled or safely returned to nature. Circular fashion is key to reducing waste and creating a more sustainable future.

3. Low Quality, Non Biodegradable Fabrics

Fast fashion has influenced activewear, leading to pieces that quickly lose shape, elasticity or colour.

In addition, many of these fabrics are non biodegradable, meaning they can take decades or even centuries to break down.

What to look for instead:
Invest in high quality, biodegradable activewear that is designed to last and, at the end of its life, can safely return to nature without leaving harmful residues.

Why Choosing Better Activewear Matters

Activewear is part of your daily life, from workouts to travel to everyday wear. Choosing sustainable activewear is not just about the environment, but also about your personal wellbeing.

When you choose consciously, you reduce exposure to harmful substances, support responsible and circular production, and invest in long lasting, high performance pieces.

The Wellicious Approach to Sustainable Activewear

At Wellicious, we design non-toxic, biodegradable and circular activewear, consciously made in Europe.

Our approach goes beyond sustainability. It is about creating activewear that is designed for a continuous life cycle, without waste.

Choose Better, Feel Better

The next time you choose activewear, look beyond style and performance. Consider what it is made of, how it is produced and what happens to it at the end of its life.
