Cotton is a genuine natural fiber: nearly pure cellulose, cleaned, combed, and spun rather than chemically rebuilt. It is breathable and absorbent, and unusually it is stronger wet than dry, which is why it stands up to years of washing. Untreated cotton can shrink a few percent on its first hot wash; washing cool keeps it closer to size.

What else should you know about Women's Cotton Activewear?

Is cotton a natural fiber?

Yes, unambiguously. Cotton grows as a fluffy hair around the cotton seed and is cleaned, combed, and spun, never chemically dissolved and rebuilt.

Does cotton shrink?

Untreated cotton typically shrinks a few percent on its first hot wash and tumble-dry. \"Pre-shrunk\" fabric has had that relaxation done at the mill; washing cool and air-drying keeps any cotton closer to its bought size.

Is cotton or linen cooler in summer?

Both breathe well. Linen runs cooler because its hollow fibers hold the cloth slightly off the skin, while cotton feels softer from the first wear. Our linen vs cotton guide compares them in detail.
