Not all cotton T-shirts are made the same.
This Premium Supima mercerised cotton T-shirt is crafted from Supima cotton, a rare extra-long staple fibre known for its strength and naturally smooth finish. We take it further with double-sided ammonia mercerisation—treating both the inner and outer surfaces of the fabric to enhance softness, durability, and colour depth.
The result is a fabric that feels clean against the skin, holds its structure, and resists the dulling and pilling that comes with regular wear.
At 220 GSM, it sits in that ideal space—substantial enough to drape well, yet breathable enough for everyday use.
This is not a trend piece. It’s designed to be worn often, washed often, and kept for years.

Frequently Asked Questions
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 cotton 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 100% 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 breathable?
Yes. Supima cotton is a natural fibre that allows air to circulate while helping regulate comfort throughout the day.
Is this T-shirt suitable for sensitive skin?
Many people prefer natural cotton because it is soft and breathable. This
T-shirt is made from Supima cotton with no synthetic fibres, making it comfortable for everyday wear. If you have specific skin sensitivities, consult your healthcare professional about suitable clothing materials.
How should I wash my Supima cotton T-shirt?
Machine wash cold with similar colours; tumble dry at low heat. Avoid bleach and dry cleaning.
If ironing is required, use a warm heat setting.
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.
