Tencel vs Organic Cotton: Non Toxic Activewear Guide

 

Introduction

When it comes to choosing eco-friendly fabrics, Tencel and organic cotton often top the list of the most sustainable fabrics. 

Whether you’re shopping for organic cotton leggings, a non toxic sports bra, or Tencel activewear, both materials offer incredible benefits—softness, breathability, and a planet-friendly footprint. 

But how do they stack up against each other? 

In this guide, we’ll break down Tencel and organic cotton, comparing their sustainability, comfort, and best uses (think Tencel leggings or an organic cotton tank top). 

Spoiler: you can’t go wrong with either.

 

 

What Is Tencel?

There are two types of Tencel: Tencel Lyocell and Tencel Modal. 

For the sake of this article, when we refer to Tencel, we're talking about Tencel Lyocell, a game-changer in sustainable textiles. 

Made from eucalyptus wood pulp in a closed-loop process, it’s a standout among the most sustainable fabrics. The production uses less water and energy than many alternatives, and nearly all chemicals are recycled. 

The result? 

Silky-smooth, super soft, and free of harmful chemicals, Tencel clothing is breathable, moisture-wicking, and biodegradable. From Tencel leggings to Tencel activewear, this fabric shines in workout gear and luxe basics alike.

 

 

What Is Organic Cotton?

Organic cotton is a natural hero of eco-fashion. Grown without pesticides, synthetic fertilizers, or GMOs, it’s gentle on the earth and your skin. 

It’s one of the most sustainable fabrics thanks to its biodegradability and low-impact farming. You’ll find it in everything from organic cotton activewear to cozy organic cotton tank tops. 

Plus, pieces like organic cotton leggings and organic cotton sports bras offer timeless comfort with a non-toxic edge—perfect for sensitive skin.

 

Tencel vs Organic Cotton: Head-to-Head Comparison

Whether you're looking for Tencel leggings or an organic cotton sports bra, let’s dive into how these fabrics compare across key factors.

Sustainability

Both Tencel and organic cotton rank high among the most sustainable fabrics, but their approaches differ. 

Tencel’s closed-loop process minimizes waste, water and pesticides, making Tencel activewear a forward-thinking choice and ideal for a non toxic sports bra or plastic free activewear.

Organic cotton, meanwhile, supports soil health and biodiversity (think organic cotton leggings or t-shirt). 

Tencel might edge out slightly in production efficiency and resource efficiency, but they both offer a non toxic and plastic-free activewear option. 

Comfort and Breathability

Love buttery-soft textures? 

Tencel clothing feels silky and excels at wicking moisture, keeping you cool during workouts in Tencel leggings and your Tencel sports bra. 

Organic cotton offers a cozy, classic softness that’s perfect for organic cotton activewear or everyday basics. 

Both are highly breathable, though Tencel’s moisture management gives it a slight advantage for sweaty scenarios.

 

 

Durability and Care

Tencel is surprisingly strong for its sleek feel, resisting pilling and ensuring durability. Tencel activewear also holds up well. 

Organic cotton is durable too, but it can wear faster with frequent washing—something to consider for organic cotton sports bras and organic cotton leggings. 

Tencel often needs gentler care (think cold wash), while organic cotton is low-maintenance and machine-friendly.

Cost and Availability

Tencel tends to cost more due to its high-tech production, though Tencel leggings and sports bras are increasingly accessible. 

Organic cotton varies widely—budget-friendly for basics like an organic cotton tank top, pricier for specialty items like organic cotton activewear. 

Both are growing in popularity, so you’ll find plenty of options online or in eco-conscious stores.

Here’s a quick comparison table:

Feature	Tencel	Organic Cotton
Sustainability	Closed-loop, low waste, toxin free, plant-based	No pesticides, natural, toxin free
Feel	Silky, smooth, stretchy, breathable	Soft, less stretch, classic
Best For	Activewear, bedding	Everyday wear, basics
Cost	Moderate-high	Varies widely

 

Tencel & Organic Cotton vs Synthetics

Plant-based Tencel and Organic cotton are far superior to synthetic fibers like polyester or nylon, and this includes recycled materials like recycled polyester and RPET. 

Polyester and other synthetic fabric that release microplastics have also been found to contain harmful toxins, another reason why we prefer non toxic activewear options like Tencel and organic cotton. 

Synthetic materials like polyester are derived from petroleum and created by a series of chemical processes. Both are favorites of fast fashion brands.

Organic Cotton: Everyday Comfort King

Organic cotton shines in daily staples like organic cotton sports bras and organic cotton tank tops. Its hypoallergenic, non-toxic nature makes it a top pick for sensitive skin or a non toxic sports bra. From gym to casual outings, it’s endlessly versatile.
