Stretchable Polyester Fabric for Activewear

You've probably wondered why some polyester leggings breathe and dry in minutes while others sit wet on the skin. Same fiber, different engineering.

This page covers stretchable polyester fabric — how we build stretch into polyester for activewear, team kit and fitness apparel, and why the moisture story matters as much as the stretch.

Where the Stretch Comes From

Polyester on its own barely stretches. We get stretch two ways:

Stretch Is Only Half the Job

Activewear polyester has to move sweat. We finish ours for moisture transport so it pulls sweat off the skin and dries at the surface — the same engineering behind our Moisture Wicking Polyester Fabric. A stretchy fabric that holds water is a bad training fabric.

How to Brief Us

Don't just say ‘stretchy polyester.’ Tell us the garment. Compression tights and a loose training tee need different elastane loads and weights. For four-way builds and swim, jump to our 4-way stretch fabric page; for a stretch-plus-UV combination, see UV Protection Stretch Fabric and the moisture wicking fabric category.
