There's More to What You Wear

The fibres, finishes and details behind every piece.

What is Supima Cotton?

Supima cotton is a premium cotton grown in the United States using extra-long staple fibres. These fibres produce a fabric that is softer, stronger and more resistant to pilling than conventional cotton.

What is ammonia mercerised cotton?

Ammonia mercerisation is an advanced finishing process that treats cotton fibres with liquid ammonia under controlled conditions. Compared with conventional mercerisation, it improves softness, durability, colour depth and dimensional stability while helping the fabric maintain its shape over time.

What is the difference between ammonia-mercerised and regular mercerised cotton?

Both processes improve cotton, but ammonia mercerisation provides a smoother hand feel, better recovery from wrinkles, enhanced colour richness and improved long-term durability. It is commonly used in premium garments where comfort and longevity are priorities.

Is this T-shirt made from Supima cotton?

Yes. This T-shirt is made using Supima cotton and finished with double-sided ammonia mercerisation, meaning both the inner and outer surfaces of the fabric receive the treatment for a refined feel inside and out.

Why does this T-shirt feel smoother than ordinary cotton?

The combination of extra-long staple Supima cotton fibres and double-sided ammonia mercerisation creates a naturally smooth surface with reduced fibre ends, giving the fabric a clean, soft feel against the skin.

Does ammonia mercerised Supima cotton shrink?

Like most natural cotton garments, a 3 to 5% shrinkage may occur after the first wash. Following the care instructions helps minimise shrinkage and preserves the garment's fit and finish.

Does this T-shirt pill over time?

Supima cotton's extra-long fibres naturally reduce pilling. Combined with ammonia mercerisation, the fabric is designed to resist surface fuzz and maintain a cleaner appearance with proper care.

Is this T-shirt suitable for sensitive skin?

This T-shirt is made from Supima cotton with no synthetic fibres or blends. This allows air to circulate while helping regulate comfort throughout the day. If you have specific skin sensitivities, consult your healthcare professional about suitable clothing materials.

Why doesn't South Ethos use large logos?

South Ethos believes quality should be recognised through craftsmanship, materials and fit rather than prominent branding. The focus is on timeless design and premium natural fibres.
