Quality You Can Count On

For decades, Underworks has been creating reliable essentials that combine comfort, durability and value. Thoughtfully designed and made from quality materials, our socks are built to deliver lasting comfort and performance, wash after wash.

We believe that creating durable, high-quality essentials is one of the simplest ways to reduce unnecessary waste. By making products that are built to last, they don't need to be replaced as often—helping to reduce waste over time and lessen our environmental impact.

Because the products you wear every day should be the ones you can depend on.

Did You Know?

Underworks socks are fully fashioned. This means the socks are knitted into their shape by a knitting machine and there is minimal or zero yarn waste compared with cut-and-sew garments, which can produce up to 30% wastage.
Our Cottons

Our Cottons

Underworks is committed to sourcing cotton more sustainably. We are currently transitioning away from conventional cotton and increasing our use of BCI Cotton across our product range. This cotton can require less water, energy, and chemicals than conventional cotton, supporting a lower environmental impact.

The Better Cotton Initiative (BCI™)

The Better Cotton Initiative (BCI™)

We source physical BCI Cotton, which means that our products with the BCI Cotton label contain cotton sourced from BCI-certified farms. BCI supports farmers in their efforts to use water efficiently, care for soil health and natural habitats, reduce the use of harmful chemicals, and respect workers’ rights and wellbeing. Through our membership, we support BCI’s mission to help cotton communities survive and thrive while protecting and restoring the environment.

Organic Cotton

Organic Cotton

Organic cotton is grown in a way that uses methods and materials that lessen the impact on our environment, it doesn’t use any harmful chemicals and the production also benefits soil rather than damaging it.

Bamboo

Bamboo

Bamboo is derived from a wild, regenerative, and abundantly available plant species that grows naturally. It requires much less water than most other tree species to grow and it requires no pesticides and fertilisers either.

Our bamboo sock range contains viscose derived from bamboo. This bamboo is certified by EcoCert and OEKO-TEX.

Viscose and Modal

Viscose and Modal

Viscose is derived from the cellulose or wood pulp from regenerative trees such as eucalyptus, beech, and pine. Our Viscose is sourced by Canopy’s Green Shirt listed companies, this means the adoption of robust forest sourcing policies, making sure they are not sourced from endangered forest.

Modal is also made from the beech tree and are made similarly.
