What Makes a Sports Bra Sustainable?

Before we get into brand recommendations, let’s quickly cover what we mean by “sustainable.” True sustainable workout gear ticks three boxes:

1. Eco-Friendly Materials

Look for sports bras made from:

• Recycled polyester (rPET)
• Organic cotton
• TENCEL™ or bamboo viscose
• Reclaimed or deadstock fabrics

These materials reduce waste, require less water and energy, and avoid harsh chemicals.

2. Ethical Manufacturing

Sustainable brands go beyond materials.
They:

• Pay fair wages
• Provide safe working conditions
• Maintain transparency in their supply chains

Certifications to look for include GOTS, Fair Trade, and OEKO-TEX.

3. Durability and Longevity

A sustainable product is one that lasts. These bras are built to endure, helping reduce the frequency of replacement and the demand for overproduction.

How to Choose the Right Eco Sports Bra for You

1. Match Your Impact Level

Choose based on your activity:

• Low impact: Yoga, stretching, lounging
• Medium impact: Weightlifting, dancing
• High impact: Running, HIIT, circuit training

Look for features like:

• Wide straps
• Racerback design
• Underbust support band

2. Prioritise Fit and Feel

A bra might be sustainable, but if it doesn’t fit right, you won’t wear it.
Look for:

• Size-inclusive ranges
• Adjustable straps or back closures
• Removable padding (for flexibility)

3. Stick to Neutral Tones or Versatile Styles

This reduces the need to own multiple items. Neutral bras can double as crop tops or layer easily under gym kits or casual wear.

Caring for Your Eco Sports Bras

Keeping your gear in good shape maximises sustainability and saves you money.

1. Wash Cold

Avoid hot water to preserve fabric elasticity and reduce energy use.

2. Skip the Tumble Dryer

Air drying prevents shrinkage and prolongs lifespan.

3. Use a Guppyfriend Bag

This reduces microfibre shedding from synthetics.

4. Rotate Your Bras

Don’t overuse one — give them time to recover, stretch between wears.

Why Green Gym Fashion Matters

The activewear market is booming — and with it, so is its environmental impact. Conventional bras are often made with virgin polyester and processed with toxic dyes, contributing to waste and pollution.

Green gym fashion doesn’t just feel good to wear. It:

• Reduces landfill waste
• Supports ethical labour
• Encourages mindful consumption

Even small swaps, like choosing an eco bra, help shift demand away from unsustainable practices.
