Quick Answer
Girlfriend Collective uses recycled polyester (RPET), recycled nylon, ECONYL®, cupro, organic cotton, and low-impact dyes.
These materials help reduce plastic waste, lower emissions, and support long-lasting durability.
From my experience sourcing sustainable fabrics, Girlfriend Collective is one of the most consistent brands in the eco-activewear category.

1. The Core Materials Used by Girlfriend Collective
Girlfriend Collective builds its entire brand around sustainability-driven textiles.
Here are their main materials and what they’re used for:
1. Recycled Polyester (RPET)
Made from:
- post-consumer plastic bottles
- industrial waste
Used in:
- leggings
- bras
- outerwear
2. Recycled Nylon
Created from pre-consumer waste such as industrial nylon scraps.
Used for:
- compressive leggings
- supportive sports bras
3. ECONYL® Regenerated Nylon
Produced from:
- fishing nets
- ocean waste
- discarded nylon carpets
Used for:
- higher-performance leggings
- swimwear
4. Cupro
A silky, plant-derived fiber made from cotton linter (a byproduct of cotton processing).
Used in:
- soft loungewear
- drapey tops
5. Organic Cotton
Certified organic, grown without toxic pesticides.
Used in:
- tees
- sweats
- lifestyle pieces
6. Low-Impact Dyes
Chosen to reduce:
- water pollution
- processing waste
- environmental impact
This combination gives Girlfriend Collective both performance and eco credibility.

2. Why These Materials Are Considered Sustainable
These fibers reduce environmental impact in multiple ways:
A. Waste Reduction
RPET and regenerated nylon divert waste from:
- oceans
- landfills
- industrial factories
B. Lower Energy Consumption
Recycled fibers use significantly less energy than virgin polyester or nylon.
C. Closed-Loop Potential
Materials like ECONYL® can be recycled repeatedly without losing quality.
D. Safer Processing
Low-impact dyes reduce water contamination and chemical residue.
From my work with eco-fabric suppliers, this mix represents a best-practice approach for sustainable athleisure.
