Build a Sustainable Activewear Collection with Cotton - Here’s How.
Introduction
Most activewear brands use technical polyester/nylon based fabrics because they offer stretch, durability, moisture management and a comfortable fit, making them popular choices for leggings, sports bras and performance clothing.
But the market is changing. Several brands are exploring natural and alternative fibres to develop non-toxic, sustainable, eco-friendly labels that feel different from conventional synthetic sportswear.
Cotton is one of the materials creating this opportunity. From relaxed-fit 100% cotton workout clothes to stretchable cotton-spandex leggings, brands are finding different ways to use cotton in activewear.
For fashion startups, this opens up an interesting product category. You can start with simple cotton workout essentials, explore organic cotton or develop fitted activewear using cotton-rich blends.
Let's look at what established brands are doing and what you can consider for your own collection.
1. Real-Life Use Cases in Sustainable, Non-Toxic Activewear
Many consumers are becoming more conscious of the materials that come into contact with their skin, particularly in women's clothing. Concerns about textile chemicals and potential endocrine-disrupting substances have encouraged brands to explore safer material choices.
Here are three brands exploring alternative fibres for activewear:
Tripulse: Uses Tencel Lyocell in selected activewear styles. Its collections focus on comfortable movement-focused clothing using alternative fibres.
BAM: Uses bamboo-derived viscose for leggings, tops and other activewear essentials. Its products are designed for comfortable everyday movement and low-impact activities.
Boody: Uses bamboo-derived viscose in leggings, tops and other comfortable activewear basics.
Insights for emerging brands
You do not have to build your entire collection around polyester or nylon. Alternative fibres can help you create a distinct product range, particularly for yoga, Pilates, walking and everyday activewear.
However, always check fabric composition, processing standards and chemical-safety reports before making non-toxic claims.
2. 100% Cotton Activewear Without Stretch - Use Cases
Here is an interesting development: activewear does not always need spandex.
Some brands are using 100% cotton to create comfortable workout clothing without adding synthetic stretch fibres. This approach works particularly well for relaxed silhouettes, everyday movement and low-impact activities.
Kshm: The brand demonstrates how 100% cotton can be used for activewear-inspired clothing without added stretch. Its approach focuses on cotton-based comfort rather than conventional compression-focused sportswear. The brand claims to make Eco-friendly, ethical, and movement-friendly comfort wear blending ancient spiritual/cultural inspiration with modern design silhouettes.
Cottonique: Offers 100% organic cotton yoga and athletic clothing, including tops and leggings. Its products cater to consumers looking for clothing made without synthetic stretch fibres. It claims that its Hypoallergenic apparel is designed for sensitive skin, are free from common irritants like latex, spandex, and harsh dyes. It supports individuals with eczema, psoriasis, and allergies.
KEAN Recovery: Its Recovery collection uses 100% GOTS-certified organic cotton for activewear designed around everyday movement and post-workout wear.
How do these brands manufacture activewear without stretch?
The answer is in the fabric construction and garment fit. Single jersey, interlock and rib fabrics offer different levels of mechanical stretch through their knit loops, while relaxed fits and carefully designed patterns provide room for movement.
For startups, this approach can work well for:
Cotton workout T-shirts and tanks
Relaxed-fit yoga tops
Walking and everyday activewear
Cotton joggers and sweatshirts
Conventional cotton can also be a practical starting point when developing a collection with lower production quantities. Organic cotton offers a stronger sustainability proposition but generally involves higher fabric MOQs.
3. Cotton-Spandex - strong emerging activewear category
If you want to manufacture fitted leggings, sports bras or yoga sets, 100% cotton may not provide enough stretch. This is where cotton-spandex becomes useful.
Cotton-spandex combines the softness and breathability of cotton with the elasticity of spandex (also known as elastane). It offers a cotton-rich alternative for brands that want to move beyond conventional polyester-spandex activewear.
The amount of stretch depends on the percentage of spandex in the fabric. Here are three compositions to explore:
Fabric composition | Stretch potential | Suitable products |
95:5 Cotton Spandex | Light to moderate | Tanks and fitted T-shirts |
92:8 Cotton Spandex | Moderate to high | Yoga tops and leggings |
88:12 Cotton Spandex | Higher | Fitted leggings and sports bras |
These are starting points rather than fixed specifications. Your fabric mill should test the actual stretch and recovery before bulk approval.
Brands Using Cotton-Spandex for Activewear
Several brands are already exploring cotton-rich blends for fitted activewear.
MATE the Label: Uses 92% organic cotton and 8% spandex in its Organic Stretch collection, including leggings and sports bras.
Laine Hill: Uses a 92% organic cotton and 8% spandex blend for cotton-based sportswear, including leggings and bras.
Tuna Active: Its AHAM® range uses 95% cotton and 5% spandex, offering another example of cotton-rich activewear.
Is Cotton-Spandex as Durable as Polyester-Spandex?
Not necessarily. Cotton-spandex offers softness and moisture absorption, while polyester-spandex generally provides better durability, moisture wicking and greater suitability for high-intensity workouts.
Cotton-spandex absorbs sweat rather than moving it away quickly, so garments can feel heavier and take longer to dry. It is better suited to yoga, Pilates, walking and low-impact activities than demanding performance training.
How can stretch recovery be improved in cotton-spandex activewear?
Using compact cotton yarn helps reduce loose fibres and pilling. Consistent spandex feeding during knitting helps the fabric stretch evenly and return to its original shape after use, reducing looseness around the knees and waist.
Can Cotton Fabrics Have Wicking and UV Properties?
Yes. Mills apply specialised moisture-management finishes to improve cotton's wicking and drying performance, along with UV-protective treatments; ask for relevant moisture-management and UPF test reports before making performance claims.
4. The right GSM for Cotton-based Activewear?
Fabric weight is another important decision when developing your collection. GSM (grams per square metre) affects thickness, coverage, drape and the overall feel of a garment.
Here are some useful starting points:
GSM | Fabric construction | Suitable products |
150–180 GSM | Single jersey and lightweight interlock | Workout T-shirts and tanks |
180–220 GSM | Interlock and cotton-spandex knits | Yoga tops and lightweight leggings |
240–260 GSM | Heavyweight interlock and cotton-spandex knits | Structured leggings and fitted bottoms |
For joggers, tracksuits and sweatshirts, you can also explore 100% cotton fleece and French terry ranging from 280-350GSM.
Fleece has a brushed inner surface for warmth, while French terry features absorbent inner loops, making both suitable for relaxed-fit activewear.
Remember, GSM alone does not determine fabric quality.
Always check opacity, shrinkage, stretch recovery and wash performance before approving your fabric.
