Supima Cotton Guide

Supima is an incredibly low-energy, low up-keep fibre which makes it ideal for crafting into wardrobe staples such as our men's t-shirts and face masks. These are intended to provide the wearer with a lightweight product that will not require consistent hard washing but will maintain its luxe surface texture and handle.

Supima cotton is also renowned as an exceptionally soft and luxurious fabric.

This guide talks about the benefits of Supima cotton, how it is made, and how to take proper care of it so that you can have it in your wardrobe forever.

How Is Supima Cotton Made?

Supima cotton is derived from the Gossypium barbadense species, which is a distinct variety of cotton plants. Supima cotton is renowned for its long, strong fibres, which produce a soft, resilient, and long-lasting fabric.

Growing Supima cotton plants is the initial step in creating this luxurious material. The plants are cultivated in agricultural fields in the southwestern United States, mainly in California, Arizona, and New Mexico. The cotton is collected either manually or by machine before going through the ginning process, which involves separating the fibre from the seeds.

Once the ginning process is complete, cleaning and carding of the cotton fibres are next to remove impurities and ensure a stronger bonding of the fibres. These fibres are spun into yarn to produce several types of fabrics, including Supima cotton.

The yarn is then interlaced to form the fabric, and the fabric is finally finished with dyeing, printing, or softening. In the last step, cotton is cut and stitched into garments and home linens.

Where Our Supima Cotton Is Sourced From?

 All of the Supima cotton used within our knitwear is ASA (American Supima Association) approved which means that a select group of specialists have confirmed that the fibre quality meets the standard, and the starting fibre is fit for the end customer’s needs.
Instead of manufacturing on a large, industrial scale, farming Supima on a smaller, more traceable size allows the end product to be steeped in traceability and being a family-owned business ourselves, their ethos of co-operative collaboration is something we’re invested in continuing.

 Benefits Of Supima Cotton


1. Sustainable

Unlike regular cotton, which is often cultivated on an incredibly vast scale, Supima cotton is grown on approximately 500 family owned and operated farms. This is to ensure that the high standards of this fibre are consistently met. The use of state-of-the-art technology in the form of GPS tractors and satellite tracking not only allows the farmers to monitor their crop growth but guarantees that there is as little impact on the environment as possible.


2. Breathable


Like standard cotton, Supima is an incredibly breathable fibre, keeping you cool and dry for longer. Unlike synthetic fibres and blends which trap air, leaving the body feeling hot and clammy, air travels freely throughout a piece of Supima cotton knitwear which will provide the wearer with a comfortable layer that will allow the skin to breath.


3. Resilient

Supima cotton is twice as strong as regular cotton which makes it perfect for creating ultra-strong, durable knitwear that will keep its shape for longer. It has a natural amount of stretch that will allow for unrestricted movement and whilst cotton will tighten when damp, leaving it to lie flat and gentle manipulating the fibres will mean that the silhouette remains intact. 


4. Ultra-Soft and Skin-Friendly

The additional fibre length found in Supima cotton (1.5 inches vs 1 inch) provides the wearer with an ultra-soft surface texture and durable fabric. When cared for correctly (we recommend washing at 30 degrees or below), your Supima cotton knitwear will continue to get softer over time. Cotton has naturally hypoallergenic qualities and so is suitable for those with sensitive skin and allergies.


Is Supima Cotton High Quality?

Supima cotton is renowned for its superior softness, strength and longevity, making it one of the highest-quality fabrics.

The long and strong fibres of Supima cotton make its fabric less prone to pilling and, therefore, more durable.

Supima cotton is a popular material for clothing, bedding, and towels, highly praised for retaining its vibrant hues over time.

Does Supima Cotton Shrink When Washed?

Supima cotton tends to shrink when put in the washing machine, just like other cotton materials, especially when washed with hot water or dried at high temperatures.

Taking proper care when washing and drying clothes and textiles made of Supima cotton can help prevent shrinkage.

How Should I Care For My Supima Cotton Clothes?

  • Gently wash in cold water, or use a delicate cycle.
  • Avoid using bleach or other harsh cleaning products.
  • Do not overload the washing machine.
  • Allow your clothes to air-dry or tumble on a low heat setting in the dryer.
  • Take the item out of the dryer while it is slightly damp.
  • Lay Supima cotton clothes flat or hang them up so that they dry completely.
  • Iron on a low heat setting.
  • Follow the care instructions on the label.
  • Dry cleaning is an option for Supima cotton clothes, but it is not necessary.
